+## Reset nonce counters
+In case some tx from your bridge validator account were done outside the bridge, you might need to update nonce counters.
+
+1. ssh to your bridge node and run:
+    ```
+    $ sudo su poadocker
+    $ cd ~/bridge
+    ```
+1. stop running docker containers using the nonce by running:
+    ```
+    $ docker-compose stop bridge_senderhome bridge_senderforeign
+    ```
+1. Connect to the redis container:
+    ```
+    $ docker-container exec redis /bin/bash
+    ```
+    you should get a shell prompt from inside the docker container, similar to this:
+    ```
+    root@redis:/data#
+    ```
+1. connect to redis database by running `redis-cli`, prompt should change once again to
+    ```
+    127.0.0.1:6379>
+    ```
+1. list existing keys by running `keys *`, output should look like this:
+    ```
+    127.0.0.1:6379> keys *
+    1) "erc-native-affirmation-request:lastProcessedBlock"
+    2) "erc-native-collected-signatures:lastProcessedBlock"
+    3) "erc-native-signature-request:lastProcessedBlock"
+    4) "home:nonce"
+    5) "foreign:nonce"
+    ```
+1. delete keys containing last used nonces on both networks
+    ```
+    127.0.0.1:6379> del "home:nonce" "foreign:nonce"
+    ```
+1. exit from redis container by running `exit` twice
+1. start the rest of bridge containers:
+    ```
+    $ docker-compose start bridge_senderhome bridge_senderforeign
+    ```
+
 ## Logs
 
 If the `syslog_server_port` option in the hosts.yml file is not set, all logs will be stored in `/var/log/docker/` folder in the set of folders with the `bridge_` prefix.
