Cannot add search engine on Fennec F-Droid or Firefox

[NiNiyas]

Hi! I recently changed from chrome to fennec, and when trying to add Whoogle as search engine, I get Error connecting to Whoogle.

Fennec version: Version 98.1.1 (981120)
Firefox version: 98.2.0 (Build#2015868579)
Whoogle version: I am on benbusby/whoogle-search:latest tag.

  whoogle:
    container_name: Whoogle
    image: benbusby/whoogle-search:latest
    environment:
      - WHOOGLE_CONFIG_URL=https://search.mydomain.com
      - WHOOGLE_CONFIG_LANGUAGE=lang_en
      - WHOOGLE_CONFIG_SEARCH_LANGUAGE=lang_en
      - WHOOGLE_CONFIG_VIEW_IMAGE=1
      - WHOOGLE_AUTOCOMPLETE=1
      - HTTPS_ONLY=1

Any help would be appreciated.
