I have same issue here on two servers now and again. I had this before once back in time, and at that time it was my ISP that blocked the access. I called them and they fixed it.
So just to confirm again, they need to make sure that my servers can reach
(http://storjshare.io/), can you confirm that…??.
Yes, your ISP needs to allow access to the storjshare.io decentralised storage network.
Doing a quick search online suggests that storjshare is quite regularly blocked for hosting malware and copyright infringing materials, among other things.
