Hey there, I try to connect an iPhone via Exchange with my Sogo instance. But I receive always the error in my Nginx-Log:
2020/06/18 09:38:53 [error] 936#936: *973173 upstream prematurely closed connection while reading response header from upstream, client: 3.227.182.193, server: virmai.de, request: "HEAD /SOGo/ HTTP/1.1", upstream: "http://127.0.0.1:20000/SOGo/", host: "mbox.virmai.de" The Sogo config part is // Parameter used to set the maximum amount of time, in seconds, SOGo will // wait before replying to a Ping command. // If not set, it defaults to 10 seconds. SOGoMaximumPingInterval = 3540; // Parameter used to set the maximum amount of time, in seconds, SOGo will // wait before replying to a Sync command. // If not set, it defaults to 30 seconds. SOGoMaximumSyncInterval = 3540; The same error appears when I try to connect my Calender with Calendly (https://calendly.com) - an webapp that can be be used in Wordpress to schedule events. So I activated debugging in the Sogo-Conf: // Log file WOLogFile = /var/log/sogo/sogo.log; // Enable verbose logging. Reference: // http://www.sogo.nu/nc/support/faq/artic … -sogo.html <http://www.sogo.nu/nc/support/faq/article/how-to-enable-more-verbose-logging-in-sogo.html> SOGoDebugRequests = YES; SOGoEASDebugEnabled = YES; //ImapDebugEnabled = YES; //LDAPDebugEnabled = YES; //MySQL4DebugEnabled = YES; //PGDebugEnabled = YES; And the only error when I tried to connect to Sogo with Calendly was this line in the sogo-log: Jun 19 08:18:18 sogod [3291]: [ERROR] <0x0x55f96b329b00[WOHttpAdaptor]> http server caught: <NSException: 0x55f96af92110> NAME:NSInvalidArgumentException REASON:[NGHttpCredentials-userName] should be overridden by subclass INFO:(null) And as i mentioned in the nginx-log this one: 2020/06/19 08:19:02 [error] 936#936: *1058977 upstream prematurely closed connection while reading response header from upstream, client: 3.227.182.193, server: virmai.de, request: "HEAD /SOGo/ HTTP/1.1", upstream: "http://127.0.0.1:20000/SOGo/", host: "mbox.virmai.de" Thx for any help.
