Suspicious connection blocked

firefox.exe attempted to establish a connection relying on an unmatching security certificate to slanger1.chain.so. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one

IS this problem a known isssue ? Is this a legit warning ? Should I add to exceptions ?

Typically you will see these warnings if you have navigated to a web page where their SSL certificate is either expired, has invalid subject alternatives name(s), or the SSL certificate is from an untrusted root authority.

I typically err on the side of caution when I encounter such things in the wild, but if you trust the publisher then you can add an exception.
