Hi there,
I have been encountering a pretty strange issue. When trying to pull a docker image on a CentOS 7 machine, I'm getting following error message:
$ docker pull nginx
Using default tag: latest
Error response from daemon: Get registry-1.docker.io/.../: proxyconnect tcp: EOF
The Sophos WebFilter-Log shows:
2020:06:18-14:28:33 hostname httpproxy[6092]: id="0003" severity="info" sys="SecureWeb" sub="http" request="(nil)" function="http_parser_context_execute" file="http_parser_context.c" line="97" message="Unable to parse a http message of 130 bytes (HPE_INVALID_METHOD: invalid HTTP method)"2020:06:18-14:28:33 hostname httpproxy[6092]: id="0003" severity="info" sys="SecureWeb" sub="http" request="0xdbfc3800" function="read_request_headers" file="request.c" line="1615" message="unable to parse a http message on handler 81 (Resource temporarily unavailable)"
Meanwhile, a "curl" will run successfully. I also tried, excepting everything for the desired host, but I get the same results every time.

It'd be great if someone could help me out with this, thanks in advance,
