Expired certificate popup en-gb.appex-rf.msn.com **how to fix it?**

Norton Security | Norton Internet Security

So couple days ago i started getting popup for en-gb.appex-rf.msn.com saying certificate not valid and access blocked. Now I am ok with the blocking but would really like to get to the root cause of the issue and correct the issue.
System is win 8.1 with Chrome Version 109.0.5414.168 (Official Build) (32-bit)

Tried to research info on it and have found that there is no apparent security concern and potentially it might be related to Chrome.

Does anyone have any insight on it and what I need to do to correct the issue.

Hello @AnthonyJ_Chiarello

Norton has blocked access to https://en-gb.appex-rf.msn.com/ because
one of the issuers of the server certificate has expired.

Your connection is not private
Attackers might be trying to steal your information from **en-gb.appex-rf.msn.com** (for example, passwords, messages, or credit cards).

NET::ERR_CERT_DATE_INVALID

en-gb.appex-rf.msn.com normally uses encryption to protect your information. When Chrome tried to connect to en-gb.appex-rf.msn.com this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be en-gb.appex-rf.msn.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Chrome stopped the connection before any data was exchanged.

You cannot visit en-gb.appex-rf.msn.com right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.

All: Chrome 109 was released January 10, 2023. Chrome 109 is the last version to support this operating system. Have you considered upgrading to at least Windows 10? Windows 8.1 is no longer supported by Microsoft and is vulnerable to issues like this one. Websites will look for and try to convince users to install a bogus certificate to infect the OS.
