Unauthorized:SigV2 authorization is not supported. Please use SigV4 instead

Akeeba:internalGetBucket(): [500] Unauthorized:SigV2 authorization is not supported. Please use SigV4 instead. Hi I am trying to configure R2 with this Joomla plugin but I get the following error: "Akeeba:internalGetBucket(): [500] Unauthorized:SigV2 authorization is not supported. Please use SigV4 instead." This plugin works perfectly with AWS S3 and with DigitalOcean's Space (which is also an S3 compatible service).
