Unfortunately not ROBLOXCRITICAL. Remember you can see the guidelines here whenever you’re unsure:
https://devforum.roblox.com/t/please-read-before-posting-steps-to-report-a-bug/24388
This does not define as a fatal error as Studio does not crash or shut down unexpectedly, it’s just that the external services are refusing the requests. (Moreover, sometimes it is possible to publish or for certain users, so it does not occur 100% of the time)
If you would like to suggest changes to the critical guidelines please make a dedicated post for this in the #inception-forum category where such discussion is appropriate.
