Cannot access Discord on home wifi computer

[lman13]

I cannot access discord.com when on one of my computers connected to Rogers Ignite home internet wifi.

When I visit discord.com on this computer when connected to another wifi network, there is no issue.

When I visit discord.com on another computer when connected to my Rogers Ignite home internet wifi, there is no issue.

The error shows in both Chrome and Edge as an ERR_CERT_AUTHORITY_INVALID error.  When I open the certificate details, it says the certificate is from Rogers Communication Inc. Engineering.  There is no CA or certificate chain attached to the certificate.

If i ping discord.com from the command line, it says:

PS C:\Users\lman> ping discord.com

Pinging ignitewifiblock.rogers.com [209.148.189.22] with 32 bytes of data:
Request timed out.

...so it appears to me that something on my Rogers Ignite modem/router is blocking discord.com.

I did a full factory reset of my router and Discord worked... for a few hours.  Then I got this error again.

The device is assigned to a user profile on the Rogers Ignite Xfinity app.  But I have Advanced Security disabled and Parental Controls disabled for the user profile, so this is not the culprit either.

I'm at a loss what to do.  Any other troubleshooting steps or suggestions?

If it was your Ignite service. It should block it for all connected devices. Not just one. I don't personally know if the modem/gateway has the ability to block a website on just one device. Usually these ISP trash cans are not that advanced. Have you tried assigning the PC you are having issues with another IP address just to see if it might be that? You might also want to check your Windows firewall settings to make sure you haven't accidentally blocked Discord from being accessed specifically on your home network.
