"No functional enrichment retrieved possibly due to an error" with StringApp 1.5.0 and Cytoscape 3.7.2

I am new here and trying to get around functional enrichment using StringApp (1.5.0) and Cytoscape (3.7.2). I am following the available tutorial https://cytoscape.org/cytoscape-tutorials/protocols/differentially-expressed-genes/#/8, but I always get the error message that "Enrichment retrieval returned no results, possibly due to an error" in Cytoscape. I have tried with another tutorial dataset, still get the same issue.
Anyone who can help?
Thank you!
Mélanie
I am getting this error today too. Retrieving proteins in Cytoscape through the String app still works fine, it seems to be related specifically to functional enrichment.

neo4j Remote guide error neo4j TypeError: Failed to fetch

I try to write my own neo4j-guide as described at neo4j.
Neither my own example nor the included restaurant_recommendation.html seems to work. If I call in chrome http://localhost:8080/play/html/restaurant_recommendation.html I get a clean page.
If I call :play http://localhost:8080/play/html/restaurant_recommendation.html I get
Remote guide error
TypeError: Failed to fetch
Any suggestion what's wrong or how to analyze it?
The problem was the cors. So I installed a chrome-plugin CORS_TOGGLE which solves the problem for me.

Unknown Error using mosquitto on a new computer

Today i installed mosquitto on a diffrent pc and im getting an error, that i personally cant do anything with.
I have googled for the past 2 hours without any luck regarding the issue.
when calling
mosquitto_pub.exe -t "something" -m "something"
i receive this error message:
"Unable to connect (Lookup error.)."
From what i have been reading the usual Errors come with codes that let u track the issue but this is so vague i have no idea what the problem could be.
I have set it up on 3 other pcs without any issues and the command works without any problems.
Now on this new pc, the error comes constantly.
Has anyone else encountered this, using mosquitto in the past and knows a way of fixing it?
All Pcs are running windows 7 64bit, and similar hardware.
I identified the problem myself.
The network connection was disabled which led to that error.
