If you get the 403 error after logging into your Hostinger account, a “Network Error”, or “Connection lost” message, there are a few things you can try:
Reload the page — use the reload function on your browser or try to open a different menu section
Use a different browser — for instance, if you're using Safari, try Chrome or Firefox
Check your internet connection — switching networks may cause this error to appear temporarily. To fix it, reload your page after the network change
If the issue persists, it is likely because the IP you're connecting from has been reported for suspicious activity, also referred to as a bad IP reputation.
Public IP addresses assigned by Internet Service Providers (ISP) are usually shared among several users. This means that any report is most likely not related in particular to your online activity but may result from some other users with the same IP – for example, if they are sending large volumes of email or creating excessive traffic to certain websites.
When an IP is reported, it becomes blacklisted by one or several security services, blocking access to certain pages.
Removing the report or whitelisting the IP is not possible for a single user and can take a lot of time. In this case, you have the following alternatives:
Contact your ISP — they can check for blocks on the IP and possibly work on its removal. Alternatively, they can assign you a different IP
Once you have applied any of these solutions, make sure to clear your browser cache before retrying access.
