IP Address Mismatch on signing into Heroku CLI

Previously I could sign into the heroku command line interface with heroku login. But now I get an IP address mismatch error. How should I resolve this?

Copy and paste heroku login -i in your terminal. This is what solved it for me.

This is no longer the case when you have "authorization token" attached to your account! – Wale Jul 30 '21 at 21:44

Error: Your account has MFA enabled; API requests using basic authentication with email and password are not » supported. Please generate an authorization token for API access. – Dendi Handian Jan 07 '22 at 01:23

This works for me but instead of setting your usual password, you should use the generated token available on your account. – EFOE Mar 19 '22 at 11:08
This won't work with macOS 12 and later. You'll need to temporarily turn off Private Relay – Thomas Horrobin Apr 19 '22 at 09:54
Interestingly ... I ran this (and it failed because I have MFA enabled), but afterwards `heroku login` worked (I kept getting `IP address mismatch` after logging in via browser before). – Dan Brown Feb 20 '23 at 22:27

Just adding some detailed steps to resolve the issue

Navigate to https://dashboard.heroku.com/account/applications
In Authorizations click on create authorization button
Add description in pop up eg.heroku cli and leave expire after blank if you dont want it to expire
You will get authorization token
in cli run heroku login -i
when it prompts for password enter the authoriation token

The accepted answer (run heroku login -i) doesn't work for accounts with MFA enabled. What I did instead was to reveal my account's API key and put it into ~/.netrc like so:

machine api.heroku.com
  login <MY_EMAIL>
  password <API_KEY>
machine git.heroku.com
  login <MY_EMAIL>
  password <API_KEY>

And voila! I can now use the CLI. This worked for me with Google CloudShell.

P.S. -- I added my machine's SSH key but could not understand how to use that to configure the CLI's access. It seems hard-coded to look for API keys in ~/.netrc.

If you are using Multi-Factor Authentication you could generate an Authorization token in settings page: https://dashboard.heroku.com/account/applications

Run heroku login -i and use the generated token as password.

For accounts that have MFA.

Run heroku login, press any key to open up browser window. Copy the url and open it in incognito mode.

If you're using a Mac running macOS 12 Monterey with the Private Relay feature enabled, you'll need to turn that off while you complete the Heroku CLI authentication workflow, since that feature is obfuscating your actual IP address by proxying your traffic through a pool of IP addresses.

Thank you. This explains why it is just started happening, seemingly out of nowhere; but it had been a week or more since I enabled Private Relay. But `heroku login -i` worked. – Greg Mar 17 '22 at 02:34

This error will occur when your machine is behind a proxy if you disable the proxy temporarily then authentication will be done.

If you're using Multi Factor Authentication you have to create an API key. To do that:

Go here: https://dashboard.heroku.com/account (login if asked)
Click here:
Open the hidden file located at ~/.netrc and paste your API key in the two 'password' fields. For example, if your API key is 'a8g73nga-9vb2-0184-afbc-54fac2b66c75', then it should look like this:

machine api.heroku.com
  login your.email@example.com
  password a8g73nga-9vb2-0184-afbc-54fac2b66c75
machine git.heroku.com
  login your.email@example.com
  password a8g73nga-9vb2-0184-afbc-54fac2b66c75

The heroku CLI will now work!

New changes where added by Heroku on login. You can find the change logs here.

In case if you are behind the firewall you may need to set the proxy.

set HTTP_PROXY=http://proxy.server.com:portnumber

what does portnumber refer to, and what should it be set to? are `proxy` or `server` also meant to be place holders for some other value, or should they be interpreted literally? – Jonathan Bechtel Sep 22 '20 at 20:59
Probably due to this issue, I found that as a workaround I could just turn on a VPN, redo the login and everything worked. – user14140381 Jun 09 '21 at 15:56

If you are a Mac user on 12.3 or later, you need to open System Preferences, > Network > Wi-Fi, and then uncheck "Limit IP Address Tracking" for the duration of your authentication.

New OSX masks your IP address, and Heroku login doesn't know how to deal with it. All you need is to let Heroku verify IP before/after auth, and you'll be good to go.

This worked for me:
1/ Logout in the browser
2/ Clear cache and cookies for heroku.com (optional)
3/ Run "heroku login"
4/ Logging in the browser tab opened by the CLI

My default browser is Safari with private relay on. This was my issue. I just copied the url from the Safari browser to one of my other browsers (Brave) and it worked.

For some reason heroku login -i led to some I/O issues on Google Colab for me.

I needed to press the return key multiple times after entering the password, and that somehow made the credentials incorrect.

I had to open up a Colab Terminal to login as I would via any Linux-based shell (The Colab terminal is available on Colab Pro and Pro+).

Turning on a VPN solved it for me. It's possible the incognito browser or clearing cookies would work, too.

The issue is that my browser and CLI had different IP addresses: https://help.heroku.com/CBF0T4AJ/can-t-login-to-heroku-using-cli-getting-ip-address-mismatch#:~:text=This%20means%20that%20you%20will,the%20changes%20to%20take%20effect.

Heroku's suggestion is to set up a server proxy, but the VPN is effectively proxying all the traffic anyway, so that works.
