You just upgraded AF60LR from factory 2.4.0-GP version to 2.6.0 on one of your antennae. After a reboot now you are waiting for the antenna to connect to the remote site and it has been half an hour and nothing is happening. It happened to me. It is a Ubiquity bug.

If you are dealing with the Airfiber series then make sure both antennas are operating at the same firmware version. otherwise, you will have weird problems.

One piece of advice: Always upgrade the farthest antenna first. The reason is after the upgrade of the farthest antenna it will not connect to the other pair (the antenna closer to you). then you will go ahead and the antenna closer to you and you should still have access, so you can go ahead and upgrade that. after the upgrade, both will pair and you will have a connection.
