Intermittent browser connection issues to our confluence web application?

Question

To whom it may concern:

Starting this past Thursday (9/30) we started experiencing an issue where a user won't be able to reach our confluence web application, with the intermittent errors below.

"PR_CONNECT_RESET_ERROR" OR "Timeout while reading data from remote server during SSL handshake"

Is this a possible coincidence with the general expiration of some digital SSL certs that help fortify the web...I do recall the providers Let's Encrypt and ssl.com making a reference to it recently.

https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/

https://techcrunch.com/2021/09/21/lets-encrypt-root-expiry/

NOTE:- we haven't renewed our support license as we were planning to migrate from the server version to the cloud in the coming months

Cheers,

Yomi

So not really certain this question/answer session would be helpful for anyone else, but will leave as is!

No idea, what was done here to alleviate our problem, but we are no longer inundated with the timeouts and/or SSL handshake issues...

I didn't see anything odd outside of typical warnings/errors (i.e. email, low disk space, duplicate attachment, etc) in the "log analyzer" or 'thread diagnostics' when things weren't working externally (i.e. outside IP) vs from inside (i.e. https:/localhost).

NOTE:- I am still not convinced there isn't an issue with DNS propagation with our hosting ISP where the VM resides, since I am able to peruse the application from inside the network during the external outage

Should I be looking for anything specific directly in the apache/tomcat/confluence logs?
