Slack Integration - Notifications stopped working

[JohnnyJoker]

We have the Slack integration enabled but 2 days ago we stopped receiving notifications.

When sending a test message from the integration settings the following message appears.
The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

I've also disabled and re-enabled the integration to no avail.

The wording suggests that the problem is on the remote side of things.
Any thoughts/ideas are appreciated.

 

Cheers, Joker

Also having this issue trying to setup this integration for the first time.

Today I saw that it started working again on the 3rd of October out of the blue.

I didn't notice until today beacause for us the Slack integration is a kind of fallback to E-Mail and the App.
