Cannot register community edition with gmail.com address

New install, requested the activation code using my gmail address, repeated attempts never receive the token. Tried once with an alternate domain and the registration token came through almost immediately.

Is this expected?

the problem is specific to certain email providers I guess

If you’re referring to being blocked on the inbound side, I don’t think that’s the issue. The alternate domain I used is also hosted with Google, but using a private domain. If I had to guess, it’s n8n not forwarding the request?
