@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.
