If you can't open it, it means the IP is not pure. If there is really no way, just read this tutorial:How to use residential IP
Anyway, I can open it by changing a few IPs. Regarding serv00, as long as you need a domain name and virtual host (such as plug-in alist), whether you understand it or not, it is recommended to register it first, and then slowly understand it.

Serv00 is a free virtual hosting platform in Poland. It uses FreeBSD instead of Linux. Each account is valid for 10 years. If you do not log in to Panel and SSH for more than three months, your account will be deleted. The solution is to set up a scheduled automatic login to SSH in the vps.
Specific configuration:
- Storage space: 3 GB
- Monthly traffic: Unlimited
- Number of websites: 100
- MySQL databases: 10
- TCP/UDP ports: 3
- System processes: 20
- RAM: 512MB
- Backup: 7 days
- Server placement: EU
- Free subdomains:
username.serv00.net
This configuration may seem very low at first glance, but many applications usually only need a host and domain name, and do not require high performance, or have other plug-in solutions. Therefore, there are many tutorials about ser00 on the Internet. As long as you use search well, you will always find surprises.
Does unlimited data flow touch your sensitive nerves? Yes, it can be used to bypass the firewall!
A reminder to new users like me: this free virtual host does not give users root privileges, so many one-click installation scripts are not very useful. You need to read more tutorials, which is the price of free.

When registering, if a red prompt appears on the user name, it means there is a duplicate name. Just change it and don't look at its literal meaning.
The answer to the last question is: free
The main thing is that your IP is pure and the entire registration process is very simple.
