@subven my organization has been working on an OSS tool that we will also be offering to host as a service as soon as its ready. This would be something that would be convenient to have on cloudron. Definitely going to reach out to the help wanted section, didn't realize it existed.
@girish so I created a new WP install on a different cloudron for the domain, https://slappersonly.co -- everything seems in order now, even for people who had errors before. Meanwhile I switched the older WP install to a new domain on the original cloudron https://slaps.vip .. there do not seem to be any issues for either domain now.
Not too terribly inconvenient as the 2 sites serve different purposes for the same brand, but bizarre nonetheless.
@martinkbs Ah, I missed it that it's trying to transfer the database. Indeed, postgresql is the internal name. There is no public endpoint. What you have to do is to export the postgresql dump from the old instance and import it into Cloudron by hand. Please see https://docs.cloudron.io/guides/import-postgresql/
