user3908: My cardano node was running normal and all of sudden I get this error,
ErrorPolicySuspendPeer (Just (ApplicationExceptionTrace (MuxError (MuxIOException Network.Socket.recvBuf: resource vanished (Connection reset by peer)) "(recv errored)"))) 20s 20s
I have tried restarting the node, but the error is same.
Note: I am using testnet.

user2656: Can you provide us with your node version : cardano-node --version
And the slot and epoch number at which your node stopped syncing. Thanks
The testnet recently hard-forked into Alonzo era and if your node isn't at version 1.29.0 then you'll have issues syncing past the hardfork.
If indeed your node is outdated, download the latest binaries here : Binaries 1.29.0
Also make sure to get the latest configuration files at : Config files
A common fix is also to delete the database folder containing immutable, ledger, ...
So try this if the above doesn't apply or solve your issue (this will re-sync your node from epoch 1).
