JDBC receiver Adapter can't connect to database anymore

Question

Hello,
I am using a communication channel that used to be working a few days ago. Now It is telling me that: "Unable to create new pooled resource: DriverManagerException: Cannot establish connection to URL". The URL is correct, I set it manually each day because the name resolution doesn't work, but it wasn't as well when the channel worked.
CPA Cache refresh doesn't have any effect.
Routing is ok.
