error "processDPCommandsEx" API(Error: Err_WIS_30270)

[former_member578292]

After a long search my problem with the error "processDPCommandsEx" API(Error: Err_WIS_30270) could not be solved. Restarting the server or chaning the user security did not resolve the problem. The error occurs in the BI launch pad.
For reports that were started without problems the first time, the error occurs after 20-30 min. The same thing happens when adding queries.

How can I fix the error in the long term?

After resolving a problem in the universe, the report can now start easily.

Now third the error message on the 3rd refreshing on. The report updates itself every 5 minutes. After 15 minutes or after the 3rd refreshing the problem occurs.
