[Bug]: SSL Certificate Verification Error for MOHU Budapest (former FKF Budapest)

[bakoscsaba]

I Have A Problem With:

A specific source

What's Your Problem

Source provider for Budapest changed from FKF to MOHU. The new source address is: https://mohubudapest.hu/hulladeknaptar
In the fkf_bp_hu.py file I changed every fkf.hu entry to mohubudapest.hu. It was working for 1-2 days then the integration stopped working.

In the log I found the following error message:
requests.exceptions.SSLError: HTTPSConnectionPool(host='www.mohubudapest.hu', port=443): Max retries exceeded with url: /hulladeknaptar (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1018)')))

Source (if relevant)

fkf_bp_hu

Checklist Source Error

• Use the example parameters for your source (often available in the documentation) (don't forget to restart Home Assistant after changing the configuration)
• Checked that the website of your service provider is still working
• Tested my attributes on the service provider website (if possible)
• I have tested with the latest version of the integration (master) (for HACS in the 3 dot menu of the integration click on "Redownload" and choose master as version)

Checklist Sensor Error

• Checked in the Home Assistant Calendar tab if the event names match the types names (if types argument is used)

Required

• I have searched past (closed AND opened) issues to see if this bug has already been reported, and it hasn't been.
• I understand that people give their precious time for free, and thus I've done my very best to make this problem as easy as possible to investigate.
