Good day to all,

I had a few problems with the designer before, but I have usually been able to find a workaround… until now.

Really appreciate the help.

Thanks.

I would start by deleting the /.ignition/cache folder first, and let the Designer download all the jars from scratch.

Will do. I’m not optimistic though, since I’m able to run the designer for my other Ignition installation with no problems.

For info:

This is Ignition version 7.7.5, running on a remote Debian server.

Thanks for your help.

Different instances of the designer get their own cached information. You may be surprised. 🙂

I’d also flush the java cache, as well.

javaws.exe -uninstall

Well, did not know that. ☹

Found the error log though, and it looks to me like a network timeout issue. (correct?)
