No update... is infuriating... not sure if we've cracked first level support yet...  apparently with the engineers, but have had no sensible response.

Re: Error 520 - API Hub token exchange internal server failure.

I had the same error 18 hours ago just one time. But now it works fine again.

I didn't change anything in the flow.

Strange.....

@Masor : Has the failed execution automatically been retried at a later point or did it fail without retry but the flow kept working afterwards for new events?

Re: Error 520 - API Hub token exchange internal server failure.

Same experience as @Masor the error appeared yesterday on a number of flows but I've since been able to successfully run them now and the error has gone.  It looks like a token expiry issue, in my case the account running the flows is MFA enabled so it might be something relating to that (normally is).

Re: Error 520 - API Hub token exchange internal server failure.

Same issue here since today, with some of our flows, not all of them.  Trigger = 'when an item is created or modified' in a sharepoint list.  

Since these flows are live, very frustrating!

Same Problem here. Creating a new trigger doesn't help.
