Wierd issue with our on premise solution. We have Sharepoint 2016 and OOS hosted on different servers.
Some users are experiencing an issue when browsing sharepoint and editing a file in the web browser, after a certain amount of time they get error messages
Now they can still open the document in full Excel/Word and working on it but they can't do anything regards to document editing in the browser. Can't even view them.
Interestingly this issue goes away after about an hour.
This has to be a timeout/lockout issue but I can't find anything that would do this and found nothing fruitful on the usual searches.
There is nothing obvious about this in the ULS logs unless I am missing something.
Possibly these two messages?>
Show error dialog. ErrorType: 16 offline
HostIntegrationMessenger instantiated before full app settings ready
Any help would be appreciated.
