Question

S33 Hostgator issue cannot get email, ftp, cpanel restricted


Forum|alt.badge.img

I have been working with 3rd level support with xfinity (Comcast) and they are stumped so far. 
I have worked with Hostgator and  they state because I can access my account outside my network it's not them. 
I have tried Eero tech support and they tried a suggestion to change my IPv4 and that did not work. 

Here is the problem:

I can no longer access my email addresses (multiple addresses through same host) using Hostgator.com
Also I cannot get to www.mywebsite.com/cpanel and also cannot log onto my websites using filezilla. 

As of yesterday I could and did not have any problems and did not change any settings. 
 

When I try to use find my websit I get my IPV6 but it cannot find my IPV4. 

I can access all of the above via my iPhone on the cellular network when I turn off my WiFi. I cannot access the above using WiFi. 

I am trying unsuccessfully to connect using a desktop hardwired on my network. Windows 10 pro. 

I have an Arris surfboard s33 modem. The eero is connected to the modem has the latest firmware revision. The eero is connected to a switch.

The Arris firmware is only updated through my isp which they have done. 

So it's either the ISP (xfinity/comcast), the modem, or the router. 

Please advise if there is anything I could do with the surfboard.

The S33 is a modem only device. It does ZERO filter/traffic management/blocking. 

Absolutely zero. 

Its not the modem. 

 

did you try a different DNS server on the eero? Not sure if eero has that ability because I don’t have one. Their forums would be best to post on

Tried a vpn! Works fine. It's the host. Thanks.

If its working through a vpn, i’d check the dns on the eero. I’m not a fan of ISP’s dns services anyway

DNS on eero was changed. It appears to be blocked by Hostgator.

If the DNS on your eero was recently changed and you're experiencing issues, it's possible that HostGator is blocking access due to the new DNS settings. You can try reverting to the default DNS or use a trusted public DNS like 8.8.8.8 to see if that resolves the issue. If the problem persists, you may need to contact HostGator support to confirm if they're blocking traffic from the new DNS and request further assistance.

Thank you all for your help. 

solution found. 
fyi  I tried 8.8.8.8 and secondary 8.8.4.4

but that did not help. By going into a vpn it confirmed that Hostgator was blocking the IPV4 since the vpn ipv4 was different and I could get results. 
 

solution: Unplug Router and Modem and leave unplugged overnight. Plug modem back in the next day then the router. Checked the ipv4 and it changed. Checked my email successfully as well as accessed my Cpanel and ftp via FileZilla. 
 

I hope this helps someone in the future.
