Post by pernockham on Persistence Manager: Config File not found? ^{CODESYS Forge talk (Post)}
Ok, think I understand. The reason for the error is I try to include complex variables (FB) in the persistenced data. I will try to use {attribute 'ac_persist_exclude'} to exclude those elements.

Hi eschwellinger, I changed the name to tap2 due to network issues with Debian (I don't know why it changes the tap0 IP every time the program restarts). Anyway, I think the tap name doesn't affect the connection.

I had the same error. It took me a LONG way to figure it out, but in my case the problem was that I used LDATE_AND_TIME. It seems to be not supported, at least not in the Codesys version I used (3.5.16)

I think it is a similar issue, but different. I saw you use AWS IoT Core. AWS limits you in this - search in page here for text "Subscriptions per connection" it is 50, cannot be changed.
