It seems like BibleGateway is no longer available in countries that have GDPR regulations. Bible Gateway say they are working on a solution.
For those of you who don't have a problem with using a VPN to make the Bible Gateway server think you are in a different country then I can confirm that OpenLP will then be able to download bible passages from Bible Gateway.
Personally I have used Windscribe VPN (just the Free version), if you confirm your email address when creating an account then you get a data allowance of 10GB per month. Even 2GB would be enough for downloading the whole Bible in multiple versions! Once you have used a chapter within OpenLP it is cached so you can spend a happy half hour opening each book in the bible so that the whole bible is cached!
If you use this link to sign up for Windscribe then you (and I) will get an additional 1GB of data per month:
