Http 405 not allowed

Keithfluffy

Hi
Been using DAVx5 for a while with synology nas and it was all fine until last week. I think there was an update and now all I get is an error and no sync.

Here is the debug, it looks like the http request has changed an so now gets a not allowed response. Nothing has changed on the nas and now all our devices have the same not allowed error.

DAVx5 hasn’t changed sync requests for a long time. This looks like a server error. Do other clients still work? Also, the DAVx5 latest version is 2.5, please try with it (but I guess the problem will persist, because its probably not a DAVx5 problem).

Thanks - it turns out that the caldav service on the synology had failed. It all came back to life after a reboot.

Thanks for the update!
