Additional InformationAs another (possibly unrelated) thing... I see regular warnings of this kind, which I believe are probes by the companies who seek weaknesses in setups. The IP addresses indicate theses specific ones come from... vulnscanner.is.ed.ac.uk (one of our University Vulnerability Scanners) but I have seen them also from external companies who do this sort of probing.

These are not normally followed by the red error message reported as an issue here... but one of these warning does appear immediately before the red error message, hence me noting it here in case it might be related.

Windows Firewall can also block IP addresses as an "Inbound Rule". Lets focus on the "System.ArgumentNullException: Key cannot be null" for this issue.
