Yort,
Do you have self-signed Tomcat certs or CA-signed Tomcat certs? See my comments below.
Muhammadan,
According to your screenshots, you have self-signed certs and the error message is asking you to accept these self-signed certs if you want to login to Cisco Finesse - that's all. Agents/Supervisors should disable the popup blocker before they login so each cert opens as a new tab. On each tab, click on the certificate error at the end of the URL to view certificate.
Cisco Finesse requires the use of FQDN. Under each cert > click on the Detail tab, verify the CN is using the FQDN format. Go back to the General tab and click on 'Install Certificate'. You can automatically install the cert or you can install (place) the cert yourself. I believe, the Enterprise Trust should be sufficient.
Once you install the certs, go back to the main page (tab) and click Ok. You should be able to login now. With self-signed certs, each user would go through this process. It takes less than a minute but for less technical users, perhaps longer. You can always add these self-signed certs to a group policy... or, better yet... you can obtain CA-signed certs.
If you're having problems logging into one of the servers, then it's likely because;
1. You didn't accept or you're missing certs for the other server.
NOTE: If you look closely at the certs, they're generated by the same servers. However, different ports were referenced, thus, separate requests. Once you accept the certs, any missing certs via ports... can be accepted after you login through the gadget interface.
2. The Cisco Finesse Tomcat service is hung up.
NOTE: Sometimes this happens during HA failovers. You can try to restart this service, or you can manually perform HA failover.
