I think that was it! Here’s what I did:
- Deleted the load balancer in Digital Ocean.
- Deleted the certificate.
- Created the certificate again this time making sure to add the intermediate certificate.
- Created a new load balancer.
- Added the new certificate to the load balancer.
- Added the old droplet to the new load balancer.
As far as I can tell, you can’t update either the load balancer or the certificate so deletion/creation is required.
Thank you so much for the speedy and helpful response. I never contacted Patreon but something tells me I’d be unlikely to receive this level of support over there.
