All published websites require active license on Site.pro. Each published website periodically makes request to Site.pro service (or On-Premises website builder) to validate license. When license validation fails, website is blocked and message "Website is temporary unavailable" appears. Below are reasons why this may happen.

Obvious reasons:

• Your license has expired.
  Fix: In this case you need to renew your license by making payment.
• Your license exceeds number of live websites.
  Fix: In this case you need to renew your license by choosing bigger package and making payment.

Other reasons:

• You had website manually blocked per statistics page or per Site.pro API. You can find out whether website is blocked by going to statistics page "Domains" tab and checking state of website from right (if it is blocked, you will see green button "Blocked") or by calling Site.pro API.
  Fix: In this case you can just make opposite action by unblocking website per statistics page by clicking green button "Blocked" or per Site.pro API if you need that website to work.
• The published website is hosted on IP address which is not added to your Site.pro account. License searching during validation is made by website IP address, and if IP address is missing in your Site.pro account, license is not found and website gets blocked. Note that after some time Site.pro service automatically adds missing IPs to your account and next time website validates license, it will start working.
  Fix: To fix this issue instantly, you need to add website IP address manually to your Site.pro account into brand and then call instant website license re-validation.
• The website was migrated from one website builder to another (it can be even between different Site.pro accounts; for example, if customer is migrated from one hosting to another). If website was migrated from On-Premises to Cloud or from On-Premises to On-Premises, then published website will still have info about previous website builder it used and will keep calling it for license validation about error.
  Fix: Just open website in website builder and re-publish website so that it gets fresh website builder info. After that call instant website license re-validation.

Instant website license re-validation:

Usually, published website makes license validation request once per day (or rarer if website is working). To force website license re-validation, you need to take following steps:

• remove file "data.json" from published website located in folder "sitepro";
• open website in new browser session (e.g., in incognito tab).
