[HttpClient] Curl client always uses HTTP 2.0 even when specifying otherwise #37402
Description
Symfony version(s) affected: 4.4.10
Description
I'm experiencing an issue with random TransportException errors (seems to be server side related) so I'm attempting to use HTTP 1.1 instead of 2.0. The problem is, HttpClient always seems to use 2.0 even when specifying otherwise.
I have the following in framework.yaml:
http_client:
max_host_connections: 1
default_options:
http_version: '1.1'
I also tried passing http_version => '1.1' to the $options parameter of request, still uses 2.0. Is there something I'm missing?
If I disable http2 on the httpd side (nginx) then it uses 1.1 as you'd expect. I should still be able to use 1.1 if 2.0 is enabled server side though right?
