Constant "Site Can't Be Reached" errors only while on Rogers' network

[luvsql]

I ONLY have this issue when connected to my Rogers wireless and just to be clear I have unplugged my router many times, rebooted my laptop many times, it's Rogers.  

All of the Microsoft websites I use for work (https://www.office.microsoft.com..., https://forms.office.com...., documentcloud.adobe.com..., and so on and so on) I get Site Can't be reached.  I have to refresh a few times and then they work.  My apps that connect to O365 constantly show errors and timeouts.

If I take my same laptop and simply disconnect from Rogers wifi, and connect to my mobile hotspot of my Bell cellphone, never, ever do I get these errors.  Not once.

If I take my same laptop to work, never, ever do I get these errors.

Every single time I work from home since the last 10 days, constant problems and ONLY on Rogers.  

I contacted Rogers support and after 2 days, no one has looked into the issue and they keep telling me they'll look into it.  

I can't keep using my cellphone just to work.

Hello, @luvsql 

Thank you for posting your concern to the community.

This is the first time we are seeing this specific issue reported. There maybe a setting on the modem that is blocking these websites. You can perform a factory reset on your modem to ensure the settings are reset to default. You can find the steps on how to reset the modem here.

Let us know if issues are persistent after the reset.

I'm having the same exact issue.  Some website cannot be reached if on Rogers Internet but had no problem on my cellphone's Virgin (Bell) hotspot.  I contacted Rogers but was told to check my settings because Rogers modem don't block websites and no other support was given.  This can't be my settings because without changing any settings, I can reach the same website with Bell.

I just fix this issue by turning OFF the "Ignite Advanced Security" feature on the HomeConnect App and now able to reach all the websites that I was having problem reaching before.

I have advanced security solutions enabled and I am able to hit the forms website, but the office one is showing that the certificate is not matching the name of the site, so there's other security issues there. There could be something else at play maybe?
