I had this same issue when working on an Ubuntu server  I was getting the following error  deploy my-comp    docker login -u my-username -p my-password WARNING  Using --password via the CLI is insecure  Use --password-stdin  Error response from daemon  Get https   registry-1 docker io v2   dial tcp 35 175 83 85 443  connect  connection refused  Here are the things I tried that did not work   Restarting the docker service using sudo docker systemctl restart docker Powering off and restarting the Ubuntu server  Changing the name server to 8 8 8 8 in the  etc resolv conf file  Here s what worked for me  I tried checking if the server has access to the internet using the following netcat command  nc -vz google com 443  And it returned this output  nc  connect to google com port 443  tcp  failed  Connection refused nc  connect to google com port 443  tcp  failed  Network is unreachable  Instead of something like this  Ncat  Version 7 70   https   nmap org ncat   Ncat  Connected to 172 217 166 110 443  Ncat  0 bytes sent  0 bytes received in 0 07 seconds   I tried checking again if the server has access to the internet using the following wget command  wget -q --spider http   google com   echo     And it returned  4  Instead of  0  Note  Anything other than 0 in the output means your system is not connected to the internet I then tried the last time if the server has access to the internet using the following Nmap command  nmap -p 443 google com  And it returned  Starting Nmap 7 01   https   nmap org   at 2021-02-16 11 50 WAT Nmap scan report for google com  216 58 223 238  Host is up  0 00052s latency   Other addresses for google com  not scanned   2c0f fb50 4003 802  200e rDNS record for 216 58 223 238  los02s04-in-f14 1e100 net PORT    STATE  SERVICE 443 tcp closed https  Nmap done  1 IP address  1 host up  scanned in 1 21 seconds  Instead something like this  Starting Nmap 7 01   https   nmap org   at 2021-02-16 11 50 WAT Nmap scan report for google com  216 58 223 238  Host is up  0 00052s latency   Other addresses for google com  not scanned   2c0f fb50 4003 802  200e rDNS record for 216 58 223 238  los02s04-in-f14 1e100 net PORT    STATE  SERVICE 443 tcp open https  Nmap done  1 IP address  1 host up  scanned in 1 21 seconds  Note  The state of port 443 tcp is closed instead of open All this was enough to make me realize that connections to the internet were not allowed on the server  All I had to do was speak with the team in charge of infrastructure to fix the network connectivity issue to the internet on the server  And once that was fixed my docker command started working fine  Resources  9 commands to check if connected to internet with shell script examples That s all  I hope this helps

It s clearly a proxy issue  docker proxies https connections to the wrong place  Bear in mind that docker proxy settings may be different from the operating system  and curl  ones  Here s how I managed to solve the issue   First of all  find out where are you proxying your docker https requests     docker info   grep Proxy Http Proxy  http    lt my proxy server gt  8080 Https Proxy  https    lt my proxy server gt  8080 No Proxy  localhost 127 0 0 1   and double check your https settings   In my case  I realized that the  Https proxy  was set to https       instead of http        so I corrected it in  etc sysconfig docker file  I m using RHEL7  and  after a docker restart with     systemctl restart docker   the proxy variable shows up succesfully updated     docker info   grep Proxy Http Proxy  http    lt my proxy server gt  8080 Https Proxy  http    lt my proxy server gt  8080 No Proxy  localhost 127 0 0 1   and everything works fine  -
