i just wanna confirm i'm having the same errors.

Trace logs: https://privatebin.net/?6b7ac59487bdb116#D5HiYPCJ2mvRG5NbZy6J82yeQtCL2vwfwd8Z7j6Scpqf

At first glance it appears to be a rate limiting issue, which explains why sometimes the "Test" function works (but not always), also explains why even after "Test" did occasionally work, a followed "Save" would fail.

[mynameisbogdan]

The "solution" is to avoid using test before saving.
