Issues with Parkour verification
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In this case (which is rare as it's caused by changing the certificate provider and it is not commonly listed), the certificate issuer is not recognized as dissect throws this error:

.. code-block:: console

requests.exceptions.SSLError: HTTPSConnectionPool(host='parkourURL', port=443): Max retries exceeded with url:
/api/analysis_list/analysis_list/?flowcell_id=XXXXXXXXX (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate
verify failed: unable to get local issuer certificate (_ssl.c:1007)')))

then, the new certificate needs to be added in the system (i.e. for CentOS 7, copying it to /etc/pki/ca-trust/source/anchors/ and run "update-ca-trust").

Finally, the cert field under the parkour header in the configuration file needs to point to the file copied in the anchors directory.


Other issues
^^^^^^^^^^^^
It can happen that the pipeline just crashes. A point of entry there would be to have a look at the log files. These are written per flowcell.
