Hi All,Today I tried enabling http/2 on haproxy 1.8.4. After enabling all requests to a certain backend started to give 400's while requests to other backend worked as expected. I get the following in haproxy.log:
Feb 21 14:31:35 localhost haproxy[22867]: 2001:bad:coff:ee:cd97:5710:4515:7c73:52553 [21/Feb/2018:14:31:30.690] backend-name/backend-04 1/0/1/-1/4758 400 1932 - - CH-- 518/215/0/0/0 0/0 {host.name.tld|Mozilla/5.0 (Mac||https://referred.name.tld/some/string?f=%7B%22la_la_la%22:%7B%22v%22:%22thingy%22%7D%7D} {} "GET /some/path/here/filename.jpg HTTP/1.1"
The backend server is nginx which proxies to a nodejs application. When looking at the request on nginx it gives an HTTP 499 error.
Is this a known issue? Or, is this a new H2 related issue? Anyway I can do some more troubleshooting? Greets, Sander
