I think the location is not the problem, but i have no idea whats the real problem is. When i use this fallback pool config, i can only mine on a non supermultipool.
After 1 minute i mine on chunkypools, all 3 super stratum dont works for me.
{
"pools" : [
{
"url" : "stratum+tcp://euwest.supermultipool.com:3333",
"user": "SjCB4NqaxJc9kYSmPsXKhgznPqSzDq1SWU",
"pass": "xxx"
},
{
"url" : "stratum+tcp://useast.supermultipool.com:3333",
"user": "SjCB4NqaxJc9kYSmPsXKhgznPqSzDq1SWU",
"pass": "xxx"
},
{
"url" : "stratum+tcp://ca.supermultipool.com:3333",
"user": "SjCB4NqaxJc9kYSmPsXKhgznPqSzDq1SWU",
"pass": "xxx"
},
{
"url" : "stratum+tcp://us-east.chunkypools.com:1177",
"user": "xxx.1",
"pass": "xxx"
}
],
may be there is a problem on your side as the stratum is working fine for me , never had any problem.If there is something wrong with the pool then it will reflect to all of us.
