Check-in Perforce server, Open a Command prompt and check below things

U:\>p4 -ztag info

U:\>p4 user -o swarmuser

Check-in Swarm application server and update the correct token value in config.php file

cat /opt/perforce/swarm/data/config.php
/* WARNING: The contents of this file is cached by Swarm. Changes to

* See the documentation on the 'Swarm config cache'.
return array(
'environment' => array(
'hostname' => 'swarm-server',
'p4' => array(
'port' => '',
'user' => 'swarmuser',
'password' => '9B89D59291C8DCABBA702A14F8377164',
'auto_register_url' => false,

Now delete cache from Swarm server

cd /opt/perforce/swarm/data/
rm -rf cache

Restart apache server

service apache2 restart

Few more commands to check the status from the Swarm application. below command works then token is working fine.

/opt/perforce/bin/p4 -u swarmuser -p perforce-server:1666 -P 9B89D59291C8DCABBA702A14F8377164 login -s
User SwarmAdmin ticket expires in 146009 hours 54 minutes.

Another way to generate a new token value as below

1. login the swarm user
/opt/perforce/bin/p4 -p perforce-server:1666 -u swarmuser login -a

2. get the user’s ticket
/opt/perforce/bin/p4 -p perforce-server:1666 -u swarmuser login -ap

3. Clear the cache
curl -u “swarmuser:ticket-value” -X DELETE “https://myswarm.url/api/v9/cache/config/”
# substitute ticket-value with the output from step 2

That’s it. it will resolve the issue.
