Howdy,
We are running CF2021 on Win2019 Server Datacenter. Over the past couple of weeks we have started seeing intermittent connection falures to some of our third party partners, like our payment processor, and other partners. CF is using TLS1.3 to make these connections, and if we immediately try to connect again when we get a connection failure, it almost always connects successfully. Sometimes it goes through fine without having to retry, so it is an intermittent failure.
One thing we have observed is that many, id not all of the failures appear to be trying to connect with a pre-shared key (PSK), while the successful retries do not (presumably CF drops the PSK when the connection failure occurs).
Is anyone else seeing something similar or has seen this?
One suggestion raised was to turn off TLS1.3 and fall back to 1.2. I assume we can do that using JVM command line args in the CFadmin and then restart?
Appreciate any help and suggestions.
As near as I can tell, we are current on CF updates.
Thank you for your time and attention.

The Package Manager page seems a little flaky. I click "Check for Updates" under Core server and it says there are no updates. Click it again and it says there are three. Click it again and it's back to no updates.

CF version is

I was told we had updated several weeks ago, because of log4j, but it looks like this might not be the latest. I do know we implemented the log4j workaround then.
Java version is 11.0.1, CF is pointing to the JRE that comes with the installer.

Your environment is lagging behind in terms of updates. I would suggest you
Who knows, perhaps when you're done, your original problem will go away.
