One more step errors

I can access all sites in normal conditions.But when I switch my modem to bridge mode, I cannot access some sites… what is the reason of this? (One more step error)

Do you use 1.1.1.1 for your custom DNS servers configured at your router interface?
Is it DSL/Wan/4G connection?
Any Firewall or port forwarding enabled?

Could you please reply with a screenshot what do you get when you visit this page:

I get the same error with 1.1.1.1 and no 1.1.1.1.

My connection is DSL.

There are firewall and port forwading.

I can only visit the site tomorrow, then I’ll immediately share the screenshot, thanks in advance
