I own this board.  It was not working earlier this morning, started working again a few hours ago.  Now updates are again showing this error.

 

Perhaps there's a bad deployment? 

 

I tried restarting, clearing browser cache, using another browser.

It seems updates to board from the mobile app work. Or at least there are no errors and comments and update seem to be persistent. 

 

Any ideas on current issues here? They are intermittent it seems but last several hours.

 

 

Java script console shows `403` on attempt to post comment etc

Hi @razzlegames Welcome to the Community!

A 403 in the browser (especially on the comment/update endpoint) usually points to a session/auth or network filtering issue rather than a normal 'cache' problem.

Since the mobile app works, I’d try logging out, clearing site data for trello.com + Atlassian login, and testing in an incognito window with extensions disabled.

Also, try a different network/disable VPN in case something is blocking Trello API calls.

Hope it helps 🙌
