HAProxy failing to redirect some sites

[Taomyn]

Another "since upgrading to 20.7.2" issue to report I'm afraid, I have reported this on Github but wanted to place the issue here in case anyone else can help.


I have two subdomain site redirections that get reported in my browsers (I have tried many), as "ERR_HTTP2_SERVER_REFUSED_STREAM" - both sites were working fine pre-20.7.2


The HAProxy has little to say, more info on Github, and I have rebooted just to be sure.


Any ideas because the latest I have found affects my wireless APs? Is it possible to revert the HAProxy plug-in so I can test that if that's the cause?

I just tried disabling HTTP/2 on HAProxy and I get further but then constant errors from the sites and messages like ERR_EMPTY_RESPONSE

I finally got around to switching from LibreSSL to OpenSSL then rebooted for good measure, and can report that from internal all the sites that were failing to work are now all fine again.


I did first try upgrading to 20.7.3 but that itself made no difference.
