As I mentioned in the title, foreign user got the ERR_CONNECTION_TIMED_OUT even though the site was availiable to access in my country. I asked about this problem to ssl company (domain and http company), but they replied that "It would be related to hosting company". Thus, I am asking in this community. I have opened the 9988 port, and it works perfectly well except for access from foreign users. How can I solve this?

Can you run ping test from the clients' machines to the server machine? In other words, can the client machines communicate with the server?
Can you also check if the port 9988 is being blocked in the clients' machine?
On top of these, there can be many reasons behind the ERR_CONNECTION_TIMED_OUT error code. Maybe a webpage like below can be helpful.

Oh... You mean that the fault might be on a client machine? like.... outbound rules about 9988 port of client computer for examples...?
Anyway, I will try to figure out the problem with attached url. Thank you...!

The error "ERR_CONNECTION_TIMED_OUT " is mostly a warning that the system hasn’t been able to connect to the server over the network. The server and the system share the data packets. A countdown or timer starts when a user asks a website for access. In case the request doesn’t reach the user before the timer runs out, the issue appears.Some common reasons for the error are as follows:-
1) Service has Timed Out
2) Non-existing Server
3) Too Much Network Infrastructure
4) Not Being Able to Share Information
5) Multiple Interferences
There are many different ways to fix the error which should be understand properly in detail. Hope it helps!
