Redundancy Tag Providers Slow Switch Over

Hi there. I have two gateways configured in redundancy which actually works fine, whenever the master gets a failure it switches over to the backup as expected. The problem I am having is that when the Master becomes available again, at the moment of the switch over back to it the tag providers “disappear” as if they would be restarted or something on the master and takes about 6 or 7 minutes for them to be available again. Has anyone experienced this? My ignition version is 7.9.5 and the gateway has about 20K tags on multiple devices.
