Forerunner 945 failed to pair with Garmin connect

same as me, did you get any help?

i am facing the issue since the 11.6 FM update.. worked perfectly fine for two years and now wont connect to my android phone no matter what I do.

Make sure you got the correct location/country setting in your Garmin Account: https://www.garmin.com/account/profile 

Remove the watch from bluetooth devices in your phone and then open Garmin Connect and add device.

Thanks, I doubt country /region is  the cause although it is set right, have tried all the trouble shooting as stated and raised a ticket with support.

It sounds odd with the country setting but it actually has an effect on the pairing. No idea why. Maybe it got something to do with regions. The pairing will not work if you change country to an APAC country if you are in a country in another region.

I've only heard about it for Forerunners.

Suddenly, my 945lte stopped automatically reconnecting to my android. I have had no issues in the past. I assume I have updated some software because if I go out of Bluetooth range I have to go through the whole process of reconnecting my phone. Very annoying and time consuming and missing texts because I didn't notice it did not reconnect automatically. I have deleted Garmin connect and reinstalled to no avail 

Update as of 9thMay 2023. The watch gradually degraded (which is very surprising and Unusual). First it would not connect to my phone and despite all trouble shooting with Garmin Support - Reinstallation of Garmin connect, soft reset of watch, hard reset of watch, tried pairing with another phone and finally a complete battery drain and charge and hard reset it started behaving erratically with long boot times and then at the 3rd reset it just failed and would not start. Forever stuck on the startup screen with the green triangle. Ultimately had to take the watch to a service center and since it was 23 months old had to pay up for a replacement unit. I am told that there is a 1-2% global failure rate and "mine was just one of those". Sure - something that worked flawlessly for 23 months with out a single drop or issue turned out defective and crashed. I have now lost faith in the brand and hardware. Since I cannot afford a new unit or upgrade, the replacement (which is essentially a new unit at a lower price) was acceptable.
