Monero GPU ubuntu timeout error

I currently have a rig setup running ubuntu 16 with 4 rx570 GPUs.

I have tried to use both Claymore's crypto note miner and the sgminer to mine Monero, but I receive connection errors with both applications for tcp/ssl and stratum (and also different pools).

I am running Claymore's with the following:

Code:

./miner -o ssl://xmr-eu1.nanopool.org:14433 -u wallet_id.Miner01 -p z

I am running sgminer with the following:

Code:

./sgminer_ubuntu64 -o stratum+tcp://xmr-eu1.nanopool.org:14444 -u wallet_id -p z

With Claymore's I receive the following error:

Code:

Connecting to ssl, port 0 ...
DevFee: Connecting to ssl, port 0 ...
Failed to connect, retry in 20 sec...
DevFee: Failed to connect, retry in 20 sec...

With sgminer I receive the following error:

Code:

[05:48:51] No servers were found that could be used to get work from.
[05:48:51] Please check the details from the list below of the servers you have input
[05:48:51] Most likely you have input the wrong URL, forgotten to add a port, or have not set up workers

Clearly, there is something going wrong with the connection - but I do not know what.

Can somebody help me with a solution?
