The Omni Group Forums

Don't think that this is a configuration problem. In the meantime, my wireshark conversation looks like this (anonymized). One thing I can imagine here that may cause a problem is that my username for the webdav server is (due to the provider forcing it) something [email]XXX@web.dav[/email], i.e., with an @-sign. The other is that Omniplan is doing something wrong with the authorization. I'd be happy to provide the Omnigroup staff a test account on this server to debug this:

Just for the fun of it, this is what the conversation looks like with Omnioutliner (same account) which works fine. Though I don't quite get why also Omnioutliner always tries again without authorization info once it fails:

After that, Omnioutliner tries again with authorization:

I hope this helps to find the problem.
