The Website created in Hubspot CMS suddenly goes offline and show a "This page is unavailable. If you believe this is a mistake, please contact the website owner." Error!
As described by others, the only workaround is to unpublish, then re-publish the website! And this happens DAILY! This makes Hubspot CMS completely UNRELIABLE! Please fix this Asap if you want people to use your CMS. I'm already looking for a new supplier.
We have tested on our end with a free account and weren't able to reproduce which is why having a HAR/specific example would help our team to investigate, however I understand your decision and I'm sorry for the frustration caused by this.
