"o.h.e.jdbc.spi.SqlExceptionHelper - Incorrect string value" in cron log​

Runs will fail if your Nextflow script or Nextflow config contain illegal characters (such as emojis or other non-UTF8 characters). Validate your script and config files for any illegal characters before atttempting to run again.

Networking​

Runs fail with 503 errors​

Error 503 suggests that a service is unreachable. In the Tower context, this means that one or more of the services being contacted as part of workflow execution are unavailable. Troubleshoot this error by ensuring all required services are running and available. Establishing connection to your database is often the culprit for this error.

"SocketTimeoutException: connect timed out" error​

This problem is often observed while trying to launch workflows from a self-hosted Git server, for e.g. Bitbucket, Gitlab etc.

This error signals that the backend/cron container cannot connect to the Git remote host. This can be caused by a missing proxy configuration.

SOLUTION

Update the HTTP proxy configuration in the backend and cron environment. eg


export http_proxy="http://PROXY_SERVER:PORT"
export https_proxy="https://PROXY_SERVER:PORT"

Email server​

How to configure SMTP gateway, which does not require authentication?​

SOLUTION

Since the SMTP gateway allows sending email without the need to specify a user name and passwords, the user and password should be set to null.

Please replace the mail section in your tower.yml with the following.

mail:
  from: "${TOWER_CONTACT_EMAIL}"
  smtp:
    host: ${TOWER_SMTP_HOST}
    port: ${TOWER_SMTP_PORT}
    user: null
    password: null
    auth: false
    starttls:
      enable: false
      required: false

Unable to receive emails for TOWER_CONTACT_EMAIL​

This error occurs due to the organizational security policy on for emails.

In case you've setup the SMTP server correctly and the emails are sent correctly via Tower, but they are rejected by your organizational email ID

SOLUTION

You need to setup/configure the spf, dkim and dmarc for your domain.

For further assistance, please contact your IT staff.

Database​

Sign in fails with java.sql.SQLException in the backend log​

While trying to log in, after the authentication, the Oops... Unable to process request error message is observed.

Expand error log
io.micronaut.transaction.exceptions.CannotCreateTransactionException: Could not open Hibernate Session for transaction
…
Caused by: org.hibernate.exception.GenericJDBCException: Unable to acquire JDBC Connection
…
java.sql.SQLException: The server time zone value 'CEST' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the 'serverTimezone' configuration property) to use a more specific time zone value if you want to utilize time zone support.
…

SOLUTION

Generally, this means that the webapp is not able to connect to the database and JDBC client needs to specify the time zone value via serverTimezone.

To resolve this issue for Europe/Amsterdam time zone, please update the value of TOWER_DB_URL as shown below

export TOWER_DB_URL": "jdbc:mysql://<YOUR_DATABASE_IP>:3306/tower?serverTimezone=Europe/Amsterdam"

java.io.IOException: Unsupported protocol version 252 is observed while completed or terminated runs still display as in progress on Tower​

When a service is restarted or otherwise interrupted, this may result in invalid entries which corrupt the cache of your installation's Redis instance. If this error and behavior is observed, the key containing the invalid entry must be manually deleted in order to restore corrrect Tower behavior. Run the following commands (replace container-name with your container name):


## To check if the key exists
docker exec -ti [container-name] redis-cli keys \* | grep workflow

## This will show the hash contents of the key
docker exec -ti [container-name] redis-cli hgetall "workflow/modified"

## To delete the key
docker exec -ti [container-name] redis-cli del "workflow/modified"

Authentication​

Sign in fails with a 500 error code frontend logs while using OpenID connect provider​

Expand error log

*8317 upstream sent too big header while reading response header from upstream, client: 10.170.157.186, server: localhost, request: "GET /oauth/callback

SOLUTION

This happens when using a OpenID connect, the callback request could send too big HTTP headers causing the Tower web server to report that error message.

The solution consists of rebuilding the frontend container adding the following proxy directives in the /etc/nginx/nginx.conf file.

        proxy_buffer_size          128k;
        proxy_buffers              4 256k;
        proxy_busy_buffers_size    256k;

Using TOWER_JWT_SECRET to generate user login tokens, user sign in fails, with java.lang.IllegalArgumentException: JWT token generator secret should be 35 characters or longer in the Tower backend log.​

The secret used to generate the login JWT token that is appended to user sign-in email URLs needs to be at least 35 characters long. See here.

On-prem HPC compute environment: Exhausted available authentication method error in Tower​

This error points to an issue with the SSH credentials used to authenticate Tower to your HPC cluster (LSF, Slurm, etc.), such as an invalid SSH key or inappropriate permissions on the user directory. Check the following:

  1. Test the SSH key to ensure it is still valid. If not, create new SSH keys and re-create the compute environment in Tower using the updated credentials.

  2. Check the backend logs for a stack trace similar to the following:

  3. Enable SSH library log tracing with the following environbment variable in your tower.env file for verbose debug logging of the SSH connection:

TOWER_SSH_LOGLEVEL=TRACE
  1. Check the permissions of the /home directory of the user tied to the cluster's SSH credentials. /home/[user] should be chmod 755, whereas /home/[user]/ssh requires chmod 700.
$ pwd ; ls -ld .

drwxr-xr-x 41 user user 20480

$ pwd; ls -ld .
