Hello all, I am trying to set up the x2go HTML client on a Debian server following this instruction: https://wiki.x2go.org/doku.php/wiki:advanced:x2gohtmlclient
My setup is done with Ansible, so the setup can be reproduced. The git repo containing the role can be found here: https://gitlab.com/jbergner/ansible-x2go-htmlclient Right now, it should be considered a BETA version (using snakeoil-certificates, etc.), but that is not the point. The x2go HTML client is accessible and it seems to be starting a session. However, this session is closed shortly after the initialization. Unfortunately, I cannot seem to find out, why. May be, someone can help? From start to end of the session, I get the following in the nginx access log: 192.168.122.1 - - [10/May/2021:22:38:57 +0200] "GET /assets/x2go-plugin/IMG/x2gobg.svg HTTP/1.1" 200 10261 "https://192.168.122.126/assets/x2go-plugin/"; "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" 192.168.122.1 - - [10/May/2021:22:39:04 +0200] "POST /assets/x2go-plugin/RPC/x2gorpc.cgi HTTP/1.1" 200 2180 "https://192.168.122.126/assets/x2go-plugin/"; "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" 192.168.122.1 - - [10/May/2021:22:39:19 +0200] "GET /x2gows/50001 HTTP/1.1" 101 17 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" nginxes error log: 2021/05/10 22:38:58 [error] 1516#1516: *2 FastCGI sent in stderr: "Scalar value @out[2] better written as $out[2] at /var/www/html/assets/x2go-plugin/RPC/x2gorpc.cgi line 79.
