CMK version: CRE
OS version: Debian 11
Error message: Cannot connect to ‘tcp:IP:6557’: EOF occurred in violation of protocol (_ssl.c:1129)
I had to eliminate one site for some other reasons. When I tried to create again the site I got the following error:
If I do telnet from the central site to that site an 6557 port I succesfully connect. I have also tried to change the sites name because I put the olds name but I still get the error. Finally I have disable this option, but Im getting the same error…

I checked the web.log and Im getting this:

Anyone knows how to solve this problem? Thanks!
