TLS verification for tasks CalDav connection?

[Christian Radler]

Hi, I'm using a CalDav server (Radicale) through DAVx5. The server (well, the reverse proxy in front of it) has added TLS client certificate verification, which DAVx5 supports. But it seems that Calengoo is using a direct CalDav connection to the server, not going through DAVx5, so now task sync is failing.

Are any of the following options a solution?

1. Is there another type of task connection account in Calengoo that will go through DAVx5? I'm using the "CalDAV" type.

2. Is there a way to make Calengoo use a client certificate for the task connection?

3. Is there a way to add a custom HTTP header to all connections? I could place a key in a header and use that as an alternate method of verification.

4. Is it possible to customize the Calengoo user agent? That would also work as a header verification.

5. As a last ditch solution I can have a look at the headers currently used by Calengoo and try to verify *something* in there that's not likely to change but I'm not sure what that could be.

Thank you.

Hi,

the easiest solution seems to be to set a custom user agent. I have added such an option now under "Settings > Display and Use > Maintenance". I will send you a new version by email.

Kind regards

Unfortunately the APK you sent doesn't want to install but I look forward to this feature being added in the future.

In the meantime I'll be checking for the "CG-Android" user agent which is sent by Calengoo by default.

I've discovered that Calengoo sends some HTTP requests with user agent "CG-Android" and some with "okhttp/4.12.0", so... keep that in mind if you want to check for them.
