We recently upgraded to LaserFiche 11 from 10.4.2 (on premise). We have a small select team testing out Web Client, Office integration etc.
Post upgrade, when a document is checked out, and after 20+mins Office Integration seems to lose (and not be able to re-establish a connection to the repository. The document can then only be checked in as a new document or by closing Word, and opening again from the Web Client.
I have enabled tracing on the office add-in and found on the client and web server that there are errors re-connecting to the repo server. On the server event viewer I usually get a object reference not found and then an invalid connection and an unable to find token.
I have disabled the idle timeout on the web client in IIS and on STS on LFDS - which is not ideal, but trying to elminate possible issues one by one.
The Office Integration does not appear to have it's own timeout in the web config.
In Word - after the timeout has occured - the login dialog appears and then fails to connect and the ribbon is greyed out. As a workaround (on a local PC) I am able to close Word, open the doc again from the Web Client with the changes I made to the doc intact (from the temporary checked out doc location on my PC) as it is clever enough to see that the doc is already downloaded and checked out. And as long as I check it in before the repo connection is lost it works.
Any ideas would be helpful.
