Re: [SOGo] subscribing external ICS calendar via webapp doesnt work with unspecified error

If it is really an SSL-issue then there should be a way to disable SSL checks, because i am sure there are hundreds of self-signed or other certificates out there. Anyway: If it was an SSL issue, there should be a proper warning. Is there some way to run sogo in debug mode to get the right errormessage to proof that it is an SSL related issue? Thanks so far!

[SOGo] subscribing external ICS calendar via webapp doesnt work with unspecified error
Hi! I'm trying to subscribe an external calendar (ICS format) via the web frontend. Thunderbird can subscribe it directly, google calendar can subsribe it too, but sogo refuses the calendar stating an (unspecified) error during import. I could not find any further information in the logs (/var/log/sogo/sogo.log and any of the apache/tomcat logs). Possible reasons i found: 1. SSL When i tried to fetch the url with wget, i found out that due to an internal redirection, the host changes and so the SSL certificate is not correct. Downloading the file with firefox does not show the certificate error. Is this a SSL issue (then there should be a proper warning and a possibility to add exceptions to that)? 2. URL character encoding The URL has the format https://host.domain.com/events/ical.xhtml?locale=LOtoken=[some usual hex-coded GUID] Does sogo have problems with special characters in URLs? Any suggestions how to find the proper error message and fix this bug?
