As on my corporate network google sheets are not allowed I am trying to access it via reverse proxy from my server. All other proxy services I have in my Apache configuration work without problems.
ProxyPass /sheets/ https://docs.google.com/spreadsheets/d/xxxxxxxxxxx/edit#gid=0
ProxyPassReverse /sheets/ https://docs.google.com/spreadsheets/d/xxxxxxxxxxx/edit#gid=0
xxxxxxxxxxx in the code above represents my spreadsheet ID. I consistently get 500 internal server error, also when changing the destination url to exclude the spreadsheet id. Chrome network analysis throws this:
Referrer Policy:
strict-origin-when-cross-origin
Has anyone solved this or is it blocked by google by default?
