My remote randomly stopped working today, except for the power and volume buttons. I did some googling and found that I should re-pair my remote, but it won’t work. I’ve followed the instructions online, switched batteries, unplugged the roku itself to reset it, and checked my connection but nothing is working. When I press and hold the pairing button it flashes green but doesn’t connect to the device. I’m using the app online to get into the settings right now but do not want to pay for it once the free trial ends.
While the remote is flashing after pressing the pairing button, try unplugging your Roku device from power and plugging it back in. (the device should look for a remote when it reboots and hopefully you will see a spinning circle that says "pairing remote").
As for the Roku mobile app, make sure you are using the official Roku remote app and not a third party one. The Roku mobile app is completely free and does not have a "trial period".

what is the model number of the Roku device you are having issue with? (Settings/System/About).
It’s a 3820X - Streaming Stick 4K
I tried what you suggested a few times, but it’s still not pairing.
Thanks for the catch on the mobile app. I definitely clicked on the wrong one by accident but have the proper one now.
The 3820 has a Long-Range Wireless Receiver (LRWR) in the power supply cable that is responsible for communicating with both the network and the remote. (it creates a private, hidden network for the remote to connect to).
It is possible that either the LRWR is failing, or that your Voice remote may not be working. (not able to find the hidden wi-fi direct network).

I think I would probably try a new remote first (since seems like the Stick is connecting to internet) and see if that resolves issue. The Voice remotes start at $20 (can be found at Roku online and at Walmart, Best Buy, Target, etc) but currently the 3820 is on sale for $35, so almost makes sense to get a whole new device.

If your 3820 is less than a year old, should qualify for replacement under warranty https://support.roku.com/article/208757058

Personally, I would probably run to the store, grab a new Voice remote (or a new Express 4k+ 3941 or Streaming Stick 4k 3820) and see if the new included Voice remote connects to the existing 3820. If so, you narrowed down to bad remote and now have a spare device for the extra $10-15. If still doesn't connect, then you may have a bad LRWR cable. (these can be found at Roku for $20.

The LRWR is primarily the reason I do not care for the Streaming Stick models. This proprietary cable just adds one more troubleshooting obstacle and part that can break/cause issues.
