Make sure, your Trezor is running the latest firmware available.
After successful installation of Trezor Bridge, you should see “trezord” process running in your activity/system/task monitor. If you cannot see the process running in the background, please try to reinstall it again, from this source Trezor Wallet
Use supported browsers only. Either Chrome or Firefox, also try both in Incognito/privacy mode as well.
Clear you browsers cache.
Not only using a VPN, but also certain advanced Firewall or Antivirus settings, browser extensions (AdBlock, Privacy Badger, etc.), may cause connectivity issues, therefore please try to disable them as well.
On top of that, use only one application/website/browser tab with Trezor at a time. It is possible that they are clashing each other.
I have encountered the same issue and tried all the solutions given on this however seems none of the solution fix my issue. Any other solution you can provide?
I have done all the procedure that was mentioned I even uninstalled my anti-virus and all including adblock i have removed it clear browser cache several time tried both supported browser and incognito and privacy mode. None of this suggestion is working i have made sure that I also performed this " * After successful installation of Trezor Bridge, you should see “trezord” process running in your activity/system/task monitor.

I had the same issue and it turned out to be a Sites Access in the Yorio extension settings, the connect.trezor.io site needs to be automatically allowed, just thought I’d post it in case it helps
