Hello @SebastianB70142 ,
Nowdays this is common issue faced by multiple users . My PDI also went to Offline since few days . But dont worry in rare situation pdi dont get back online . We can just keep some patience for while . Always keep in mind if you are doing any business requirement task on pdi then always takes its backup even if task is in progress or completed so it will help in such situations . Unfortunately there is no any solution for this .

If this helps you then mark it as helpful and accept as solution .

Aditya
