Hello together, after some tests with texworks, nextcloud, owncloud, it looks like you need to activate BIG-REQUESTS extension. ( Thanks to Mike and Uli )
/etc/x2go/x2goagent.options X2GO_NXAGENT_DEFAULT_OPTIONS+=" +extension BIG-REQUESTS" Next nxagent version should fix similar error with vscode. Best Regards, Juri Grabowski
