Who Me Too'd this topic

I have a high number of sessions, for various webservers and clients, being closed due to decrypt-error. I've attempted to follow the tips from this document, but I'm still not clear on root cause:

Need help identifying why sessions are ending with message "decrypt-error"

Here are a few of the messages I'm seeing the debug logs:
