 Troubleshooting
 ===============
 
-SSL Error
----------
-
-If you're getting an SSL related error or can't seem to be able to open existing
-spreadsheets that you have access to, you might be running into an issue caused by
-``certifi``. This has mainly been experienced on RHEL and CentOS running Python 2.7.
-You can read more about it in `issue 223
-<https://github.com/burnash/gspread/issues/223>`_
-and `issue 354 <https://github.com/burnash/gspread/issues/354>`_ but, in short, the
-solution is to either install a specific version of ``certifi`` that works for you,
-or remove it altogether.
-
-.. code-block:: console
-
-   pip install certifi==2015.4.28
-
-or
-
-.. code-block:: console
-
-   pip uninstall certifi
