[Xymon] error:14082174:SSL routines:SSL3_CHECK_CERT_AND_ALGORITHM:dh key too small

[Root, Paul T]

We patched our OS on our xymon proxy servers, and now we get the error in the xymonnet test

Error output:
Unspecified SSL error in SSL_connect to https (47873/tcp) on host NNN.NNN.NNN.NNN: error:14082174:SSL routines:SSL3_CHECK_CERT_AND_ALGORITHM:dh key too small


It looks like it's some sort of issue with an openssl patch.

The machines in question are CentOS 6.9,  and xymon is 4.3.21, that we packaged ourselves.

I vaguely remember others having issues with SSL certs and xymon last year late.

Does anybody have an explanation or solution?


Thanks,
Paul.
