Same symptoms invite by email fails.

I am dealing with this issue as well and am hoping for a fix.

[Sazu-bit]

Attempted to change the https:// for a http:// but same errors being thrown by Synapse. Suspect the same is also thrown by Sydent.

[GreenFootballs]

Having the same issue. Inviting by email fails with an "unknown error."

This is hopefully fixed by #545, which should be deployed soon.

[erikjohnston]

This is deployed now. Hopefully should work now?

[coolsantino]

All fine now. Thx.
