Hello, thank you for your reply @bogikornel @TrapoSAMA . Here are my processor specifications: Intel Xeon E5-1620 v2 (8) @ 3.691GHz. Unfortunately @Andrew , I have to use RHEL 10 on my server ^^ but thank you for providing the link. I will change my processor/server.

@johnnyorange Glad I could help! Took me weeks to figure that out lol....I would caution using that in production though, not sure the security implications for accepting the older key type.

You would have to write a daemon, listing for webhooks, parse it, and then send it to Mattermost with the expected payload.
