WLC 4400 Cannot send an ARP reply

Has anybody seen this error message. "dtlArpRequest: Cannot send an ARP reply to 00:0B:85:86:4D:20" It happens when I change the WLC to lag. It works fine without lag turned on. There is about 17 aps on it. As soon as I turn it on and reboot the WLC about 10 of the aps come up. Over time the aps get fewer and fewer until there is 0 aps. Any ideas?? I have checked the switch config per cisco specs and I still have same problem. I have upgraded to 4.0.206 to 4.1.

Hi Friend,
I believe you might have reloaded the controller once after you enabled LAG? Also what is the channel-group mode set to on switch side?
Also can you paste the output of "sh interface sum" from controller?
Regards,
Ankur

Cannot send, foward or reply e-mail

I upgraded to Windows 8.1 and IE 11 and immediately could not send email (or reply or forward). I get an error message in the message space of the email form. I use Hughes.net email.

Hi,
IE11 does not use the MSIE token in its userAgent string.
Contact support at hughes.net to let them know that their software is incorrect.

Cannot send email from my iPhone or iPad. The server rejects a recepient for no apparent reason. The recipient is not new. This issue happens on reply or reply to all or froward; not a new email. What is happening?

I talked with a tech today and he said I cloud is having problems which should be resolved shortly.
In the mean time I used the .me smtp server settings which allowed me to send mail.

Cannot send/reply email on Mac and iPhone

SOMETIMES I cannot send or reply emails on my Mac, not all the time though. Went to Apple Store where a Genius helped me reset my mail app but turning it off and back on again, it worked there and then but when I got home, I'm still getting the below same message when I try to send or reply sometimes:
"Connections to the server "p08-smtp.mail.me.com" on the default ports times out.
Select a different outgoing mail server from the list below or click Try Layer to leave the message in your Outbox until if can be sent."
This happens on my iPhone as well. Sometimes when I reply to someone's email it'd just sit in the Outbox for more then a day despite numerous attempts to resend. In the end I could only delete it from Outbox and send a new one again. I tried to find answers online without luck, can someone please help?
Note that if I send/reply on iCloud website, everything works perfectly!
Many thanks!

I cannot send or reply to e-mails. The recipient was rejected by the server because it dows not allow relaying

I cannot send or reply to emails. I get an error message that reads "A copy has been put in your outbox. The recipient was rejected by the server because it does not allow relaying. Has anyone else had this problem?

Your outgoing mail server settings are incorrect. Go to the settings for the email account and look at the SMTP settings. Most likely you did not enter your user id and password. While it says "optional" that's only from the iphone's point of view; it probably isn't "optional" from the point of view of your email provider.

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts Tap on the Account, then on the red button that says Remove Account.

MAIL reply all to large message- "Cannot send message" how to get this to go away

I replied all to a large message and got the notification "cannot send message..." I usually press cancel or try again, but since the message was so large, I don't have access to either buttons. It won't allow me to scroll down and maximizing the message does not help. I have tried force quit and shutting down my computer, but everytime I reopen mail, the message pops up. PLEASE HELP!!!!

I cannot send or reply to emails

I am having problems with my emails in that I now cannot send or reply, help?

gillian
is this of sudden onset? Update of iOS perhaps?
I have seen several of this issue come through and I thought certain it had been answered definitively, but alas, I cannot find the thread I remember via search.
The one thread that has an official Apple employee participating is since the ios 8.1.2 upgrade my pop email account will not send - there are a couple of links provided for self help and a contact link if no joy.

After transferring my contacts on to my iPhone, I cannot send or receive text messages to some of them. Even if they text me, I cannot reply!

After transferring my contacts to my iPhone, I can no longer send or receive text messages from some of them. Even if they text me, I cannot send a reply!

Same problem persists also here. Have crosschecked with friend, all same settings, have deleted the contacted, created again, still that number does not receive my SMS (no question on iMessage). Can not even reply her message. This problem persists with few numbers, nothing common, different phones, different countries, different operators. All others, with different operators, in different coutries receive my messages. Even other people can send their SMS to her.

I cannot send some emails, I can reply but I cannot start an email, an error comes up in outbox stating 'does not allow relaying' please help?

Try going into Settings > Mail, Contacts, Calendars > select the account > account name , tap on SMTP (under the 'Outgoing Mail Server' heading) and then tap on your Primary Server and try entering your email account and password and see if it then works

Replying to an email from iPhone - "cannot send as address is invalid"

This seems to have started happening only recently. When an email comes in on my iPhone and I need to respond, I hit reply, type my text and when I hit send, the warning comes up "Cannot send because email address is invalid." Has anyone else had this problem or has a solution? Really thwarts the email aspect of the iPhone.
Much thanks in advance for anyone's help.

this is happening only with my gmail account...i hope it's a gmail problem.still waiting for the fix.
cheers

TS3899 Cannot reply mail -- cannot Send pictures to e-mail

Hello, Cannot reply to my e-mails and cannot send pictures to e-mail?

It's not an SMS, but if you select Multimedia Message rather than text message when you are creating a new text to send to an email address, it will send---at least it works that way on my phone. Good luck!

HT3529 I receive messages on my iPad, but I cannot send a reply. The send button will not respond to my touch.

I receive messages on my iPad, but I cannot send a reply. The send button will not respond to my touch.

It's not that you can't use the subject field, but it is very unreliable when I try to use it. Sometimes the message send button will work and sometimes it won't.
But the biggest reason to turn it off is so that you do not accidentally type your message in the subject field. You can type a subject in that field, but you still have to type the actual message in the space below the subject field.

IPhone4 when replying or forwarding mail messages i get a message that says Cannot Send Mail address rejected by the server because it does not allow relaying

When forwarding mail this is what i get
Cannot Send Mail
A copy has been placed in your Outbox. The recipent _________________(email address) was rejected by the server because it does not allow relaying.
Never had this problem before so not sure whats going on. Appreciate any help out there.

Sounds like there is something wrong with your SMTP server. Try going into Settings>Mail, Contacts, Calendars>select the email account in question, go to the Outgoing server (SMTP) and check the settings. It may be you do not have a username and password in one of the areas. The phone may say optional in a couple, but it is usually mandatory. You can also try a reset on the device, hold the sleep/wake and home buttons together until you see the Apple logo and then release. If neither of these work, then you will need to delete the account, then delete the SMTP server, then add the account back, ensuring you use your username and password everywhere, even when it says optional.

Cannot send email from non .mac server

I am only able to send/reply emails using my .mac address. My 2 other server addresses keep giving me the following message.
"Cannot send mail. One of the recipient addresses was invalid".
How can I fix this?

You should be able to send email from Safari, however I do wonder why you wish to do this and whether there is something inherently wrong with using your mail app and your iCloud address.
