AltostratusHi All,
We upgraded F5 on May 18,2024 from v12.1.3 to v15.1.8
we trying to get auth token from
/mgmt/shared/authn/login
But getting 401 error, please find the detailed error message. Can any one help me with this issue. It was working fine on v12.1.3
{"code":401,"message":"Authentication failed.","referer":"172.28.24.61","restOperationId":106134247,"kind":":resterrorresponse"}
EmployeeThe REST subsystem in BIG-IP can sometimes suffer from low user space RAM, especially with large configurations. Also there is an upgrade process that occurs immediately after booting into a new version.
It may help to change Management Provisioning to Large:
Restjavad can sometimes get into a "stuck" state where the worker processes suffer continuous timeout errors. The log files (/var/log/restjavad*) offer evidence of this behavior: search for the term "timeout" in those files.

We already set to Large.

Can you please advise how do we access that log? looks like no-one clear on our team.
EmployeeSure. The REST log files can be reviewed using bash like in this video:
You can change the log level to increase or decrease the amount of logging:

This article talks about the exact names of those log files and gives some example commands:

Finally, it may help to become familiar with Linux logging generally, as Linux is the host operating system used on BIG-IP and there are many log files that contain useful information. Here's Ubuntu's comprehensive article that should help:

AltostratusHere's the scipt which works at 12.1.3, we do use loginProviderName toms.
Can you advice where to check "/var/log/restjavad.0.log"?
F5url="https://<example.com>/mgmt/shared/authn/login"
response=$(curl -X POST $F5url \
-H "Content-Type: application/json" \
-d "{
\"username\": \"$username\",
\"password\": \"$password\",
\"loginProviderName\": \"tmos\"
}" -k -s)
echo "Response from server:"
echo "$response"
NimbostratusAre you including "loginProviderName": "tmos" in your POST? Maybe /var/log/restjavad.0.log has some additional info about the failure.
