[MM3-users] Re: admin/login/ cannot be accessed

Removing http2 from all server blocks which share the same IP address and listening on uwsgi-socket with tcpdump:

# tcpdump -i lo --direction=inout 'tcp port <uwsgi_server_port>'
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on lo, link-type EN10MB (Ethernet), capture size 262144 bytes

When launching https://mysite/admin/login to get the login screen, the conversation appears with 127.0.0.1:<uwsgi_server_port>:

11:45:31.322143 IP localhost.46912 > localhost.<uwsgi_server_port>: Flags [S], seq 138343284, win 43690, options [mss 65495,sackOK,TS val 2322576143 ecr 0,nop,wscale 7], length 0
11:45:31.322241 IP localhost.<uwsgi_server_port> > localhost.46912: Flags [S.], seq 204629092, ack 138343285, win 43690, options [mss 65495,sackOK,TS val 2322576143 ecr 2322576143,nop,wscale 7], length 0

When I enter the admin account credentials and hit login, no communication is detected by tcpdump: how can this be possible?
