I'm not sure if this is as common an occurrence for others as for me, but just in case other stackers are experiencing this too today, I figured I would make a post. The Send connection failed about 3 hours ago. I attempted to create a new connection, but got this error message:
failed to create test invoice: timeout after 45 s
It began working again a few minutes ago without any further action from me.
failed to create test invoice
is in reference to receive. If you're having issues sending, then that error is unrelated.
