Hi, It been a while and I have been getting Network Error (ConnectionError) whenever I am trying to link to my account. I have deleted the settings and netrc files, uninstalled and reinstalled wandb but nothing seems to work. My machine is an Azure machine. One further investigation, the debug log shows ConnectionRefusedError: [Errno 111] Connection refused It used to work fine and then suddenly it stopped working one day. Please could you help sort this issue. ---

Hi @alexvizgard, do you get that error message on `wandb.init()`? Also, are you trying to login to our public cloud service ([wandb.ai](http://wandb.ai)) or a private deployment hosted elsewhere? Thank you, Nate ---

Hi Nathan, Yes, I do. I am trying to use the public cloud service. Kind regards Sandipan ---

@alexvizgard, Are you able to login to `wandb` and run `wandb.init()` with your API key on another machine? You could test out a Colab if you need. If so, I would guess there is some infrastructure blocking the network traffic. Running `ping api.wandb.ai` from the CLI on the Azure machine would be a good baseline test to make sure it can establish a connection. ---

Hi Nathan, Yes, I am able to do run wandb.init() from another machine (on Azure within the same account) using the same API key. I had tried it on Colab as well. It is just this machine that it deosn’t work on. I am able to ping [api.wandb.ai](http://api.wandb.ai) from the machine. I am able to ping and receive a response from the CLI as well as from within the virtual Conda environment. The machine has been updated and the urllib library is updated as well. ---

@alexvizgard, thank you for testing. If you run in CLI `wandb login --cloud` do you get your username printed to terminal? Also, could you share more from the debug log? Preferably if you could upload it here or email it to [Nathan.kuneman@wandb.com](mailto:Nathan.kuneman@wandb.com) so I can take a look? Lastly, was there anything that changed around the time this stopped working? Upgrading `wandb` for example or any changes to firewall of the Azure machine? I’m lead to think this may be firewall related. ---

Hi Nathan, The login does return the username. I have already done this test. Please find attached the logs. Nothing had changed since it suddenly stopped working. However, in a bid to troubleshoot the problem, I had updated the machine. However with an updated different VM, it works fine. In the logs you might notice, I am using a conda environment. I have already tried without the conda environment and it still doesn’t work. With the same Conda file in a different machine it works. Kind regards Sandipan ---

Hi @alexvizgard, interesting. Would it be possible to look through the env variables that are set on the machine and see if anything is suspicious? If `WANDB_BASE_URL` is set I could see that causing this or if any env variables that relate to setting up a proxy that doesn’t exist that may cause this. ---

Hi Nathan, Surprisingly, it started working from today. Did you make any changes on your end? ---

Hi @alexvizgard, no nothing should have changed on our end. That’s interesting though. Do you want to call this solved for now and we can investigate further if this comes up again? ---
