The connection to remote server 127.0.0.2 was refused or timed out while attempting to connect.
This has been happening often. 2 things have changed. A Cox Panoramic Modem/Router as installed along with my wife's TP-Link wireless router. I also installed Windows 10 a few weeks ago. The error does not always occur, but to often.
Does it only occur on the new Windows 10 PC? Also, check your TP-Link router's internet IP address as seen here. Make sure it isn't 192.168.x.x. Not that I think double NAT is causing this problem, but might be causing others.
The COX modem died. When the Techs came they informed me I owned it and needed to get the Panoramic to replace it. Because my wife has Wireless to the Tp_link they somehow connected it to the Panoramic and she works fine. I will be gone this afternoon. Please keep the suggestions on how to access the COX and Tp-Link as well at the 127.0.0.2 issue coming.

You should have replaced it with a stand alone modem found here. How much do you pay per month for the gateway? Sounds like they tricked you, no offense. If you do decide to change to a modem, I suggest the SB8200 or S33.
As for going forward, how do you want to go? If the problem is only with Cox webmail, would you be open to using a email client like Outlook or better yet, Thunderbird? If not, you might try a different browser. Firefox is a good option and runs on a different engine then Chrome/Edge so maybe it might have a effect.
You should not be trying to connect to 127.0.0.2. It's a loopback interface address, also known as local host. If you have something trying to connect to that address, it could indicate a problem on your computer.
