I see now. It seems that the instructions that we provided updated only model urls and there are some more artifacts that need to be handled. Please try running the attached python script from inside your apiserver docker container. The script should fix all the task artifact links in mongo. Copy it to any place inside the running clearml-apiserver container and then run it as following:

python3 fix_mongo_urls.py --mongo-host 

 --host-source 

 --host-target http://<your target address and port here>
