You don't have to enter anything there, it will use the default servers to update. The field is just a list of servers, the updates must be hosted correctly on there. Steve

an attempt to better explaination I have a scenario where I need to check that two different servers are up to consider service as up If server A and server B is up - goto server B else goto server C Is that doable?, if not - can I check server A as below; If A is up go to server B if A is down go server backup server C (in this workaround scenario I will let server A check server B for me) server B is in both scenarios the endpoint for the user, but ALSO depending on A status server B is a blackbox so I can’t do anything there. messy explaination - i hope somone understands it

@gertjan ClamAV uses Icap with squid is it possible for it to do that? Icap is http. It has caught a virus on the streamer once also however. My browser itself did not catch the issue this time all ClamAV with this one. This was a iMac running desktop version M1 2021. This was me looking for math help.

@nan0tech said in HAProxy warning: Had the same issue yesterday, while learning and setting up acme and haproxy. Got it just working that i have linked my 4 servers behind haproxy. While adding a new backend and incorporating it in the frontend i got this error to. Now i added the regex with .+ as suggested in a other post here, but its not working for me at the moment. I tried lawrence systems way, just didn’t get it to work. Then i found this guy and his approach got me a working haproxy. In the youtube at 15:24 was the setup. For some unknown reason it stopt working after adding the last backend. Same - Leverage Lawrence Systems for everything, BUT HAProxy. SystemaD video solved it, and I try to do the same and point people to this video. Wish he didn't stop posting.

I am sorry to reply so late to this, but I did not access the forums for a long while because I did not have any notification about it. I managed to make haproxy work perfect only by moving to ssl redirect on haproxy and adding letsencrypt certificates to the server. I did not manage to make it work without ssl. This is anyway better practice, as traffic is encrypted and browsers and other devices will trust my servers.

@cybis thanks a lot for responding
