after htaccess Contao 2.9.1 redirects to http from https

I have been asked to take on a new site, it is Contao 2.9.1.
My experience with Contao is limited

I have configured and tested this site with an htaccess file forcing https and the site loops.
The cloud hosting vendor confirm it is the "scripts" that is resulting in the redirect back to http.

I note in the Contao built pages, there is a base href setting to http://www.domainname.com/
Where is this set, as possibly this is what is causing the issue, so I would like to override it to https://www.domainname.com

There is a redirect extension installed, but I do not find where it is set, and wonder if this could be the cause. The module appears to be https://contao.org/en/extension-list...030009.de.html

Other thoughts on where to review would be appreciated.

I would try the following:

• Switch to the HTTPS front end via .htaccess:
  
  Code:

  ---

    RewriteCond %{HTTPS} !=on
  RewriteCond %{ENV:HTTPS} !=on
  RewriteCond %{SERVER_PORT} !^443$
  RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

  ---

• Disable the [redirect] extension
• Purge the page cache (Back end "System" > "Maintenance ") and the browser cache

Thank you of the thoughts:
How do I disable the "redirect" extension? Under "extension manager" I do not see a disable option, only an uninstall option.
Under "System Settings" in "Inactive Extensions" "redirect" is listed. Does that mean it is inactive, or can be if I selected it? Once deactivated, how would I reactivate if desired?

Inactive extensions
[backend_filterwiz]
[backend_tabletree]
[browserdetection]
[calendarfield] Calendar field
[calendar] Events
[catalog] Catalog
[catalog_encrypted]
[changelanguage] Change Language

I have tried variations with the htacess and have purged "data" as available in the maintenance window, options are shown below.
Purge data

tl_version (10 entries)
tl_search (9 entries)
tl_search_index (541 entries)
system/tmp (0 entries)
system/html (30 entries)

Deselect the option again.

Excellent, thank you very much. Does the forum have a donation option to support the community?
