Mining Pool Connection Problem

Since yesterday I have the problem, that I cant connect to any mining pool. My GPU was mining and then it lost the connection and since then i become this message:

ETH: Stratum - Cannot connect to eu1.ethermine.org:4444
ETH: Stratum - Failed to connect, retry in 20 sec...

I tried different mining pools but got the same problem every time, although my internet connection is fine. I use claymoreminer if that is important. I dont know what to do now and I hope someone could please help me.

    I have a similar but not the same issue for asia1.ethermine.org where I am suddenly connecting to a host in the USA instead of somewhere in Asia.

    Here's my suggestion:

    Do a DNS lookup of eu1.ethermine.org .. it should show you a list of IP addresses.
    Try using one of the IP addresses directly instead of eu1.ethermine.org.

    Probably one of the IP addresses that got resolved from eu1.ethermine.org is not working / down.
    You can find out what IP address(es) that you were using that is no longer working in the *log.txt files.

    Here is what I have resolved from eu1.ethermine.org ( check against your own results ):

    $ dig eu1.ethermine.org ; <<>> DiG 9.9.4-RedHat-9.9.4-51.el7_4.2 <<>> eu1.ethermine.org ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 44540 ;; flags: qr rd ra; QUERY: 1, ANSWER: 8, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;eu1.ethermine.org.

    I dont think that is the problem, I have tried some of the IP addresses still the same problem. I also tried some other mining pools and there i get the same problem

    Can you actually telnet to any of the IP addresses and port number ??
    Have you tried running tshark / wireshark to see what's happening ?

    I tried now to ping the IP addresses. I pinged one of the IP addresses from my local computer. I get an successfull answer answer there. When I ping it from the mining pc I lose every package. But something like google works.

    ping is no longer a useful test to the pool, because since a few days ago, I can no longer ping asia1.ethermine.org ... even tried directly pinging the IP addresses for asia1.ethermine.org returned from DNS ... all ICMP packets lost.

    However, I remember just last week that I was able to ping asia1.ethermine.org and even tried each of the individual IP addresses returned from the DNS lookup.

    Try telnet to the host and port.
