Hi Sai,

From the above log, it seems to be the network stability issue due to which the Host is unreachable. It is trying to reconnect but it is getting failed.  
Also kindly let us know the Architecture of your current deployment and which mongodb version is been used.  
Is this the same cluster which you have mentioned in other forum ([Zstd sync up issue on new replica for mongoDB](https://forums.percona.com/t/zstd-sync-up-issue-on-new-replica-for-mongodb/21943))?

Regards,  
Parag
