SSL VPN Failed to validate server certificate (cannot access https)

Question

Hi all,
I have the next problem.
I've configured in an UC520 a SSL VPN.
I can access properly and I can see the labels, but I only can access urls which are http, not https:
I can access the default ip of the uc520 (192.168.1.10) but
When I try to get access to a secure url I get the msg: Failed to validate server certificate
I'm trying to access a Cisco Digital Media Manager, whose url is https://pc.sumkio.local:8080
Does the certificate of both hardware has to be the same?
How can I add a https?
Here is the config of the router:
webvpn gateway SDM_WEBVPN_GATEWAY_1
ip address 192.168.1.254 port 443 
ssl trustpoint TP-self-signed-2977472073
inservice

Any help would be apreciatted.
Thank you

Hi, thanks for your advise.
I'm trying to copy the certificate via cut and paste, but I'm getting a
% Error in saving certificate: status = FAIL
I dont know if I'm doing this right.
I open the https page from the DMM with Mozilla Firefox, and in options I export the certificate in PEM format.
I get a file which if I open with notepad is like
-----BEGIN CERTIFICATE-----
MIICOzCCAaSgAwIBAgIET7EwyzANBgkqhkiG9w0BAQUFADBhMQswCQYDVQQGEwJV
KoZIhvcNAQEFBQADgYEAdk7n+tJi0igrTD2o7RD9ty8MLTyHN4uk8km+7DbpEy0g
mxLY0UZswYvbj15kPdd8QbeGEdDR6SXOYePsfIRJzL0mqMON4oiUhsqAK5y2yC6R
nqy4wWQ2fGVEYAeLpb1jGKdZWpuag/CO90NMHcMiobfBh+4eTqm7kRPTEyma6V0=
-----END CERTIFICATE-----
If I try to authenticate the trustpoint, I get that error.
how can I export the certificate from the DMM?
I think that this file is not the right file.
and then, do I have to make some changes in
webvpn gateway SDM_WEBVPN_GATEWAY_1?
Should I choose the new trustpoint?
I understand that the old trustpoint is for the outside connection, no for the LAN connection.
Dont worry about me, answer when you can but I really need to fix this.
Thank you so much
