I Get "Site Can't Be Reached" When Connecting Salesforce

This error means the Salesforce workspace name you entered doesn’t match a real Salesforce instance. The workspace name is the subdomain from your Salesforce URL — for example, if you log in at https://acme.my.salesforce.com, your workspace name is acme.

Symptoms

You try to connect Salesforce from Settings → Apps or from an agent chat.
After entering a workspace name, the browser opens a new tab that shows This site can’t be reached or ERR_NAME_NOT_RESOLVED.
The authorization page never loads — it fails immediately after you click Connect.
Logging out of Salesforce, Okta, or other SSO sessions and retrying doesn’t help.

Cause

When you connect Salesforce, Gumloop asks for your workspace name. This value is placed into the OAuth URL as https://{workspace}.my.salesforce.com/.... If the workspace name is wrong — a typo, your company’s marketing name instead of the actual Salesforce subdomain, or the full URL instead of just the subdomain — the resulting URL points to a server that doesn’t exist, and your browser shows a “site can’t be reached” error.

How to Fix It

Find your real Salesforce workspace name.
- Log into Salesforce in a separate browser tab.
- Look at the URL in your address bar. It will look like: https://yourcompany.my.salesforce.com
- The workspace name is the part before .my.salesforce.com. In this example, it’s yourcompany.
Go to your Salesforce credentials page in Gumloop.
Revoke the existing Salesforce credential if one was created from the failed attempt. Click the three-dot menu next to it and select Revoke.
Click Connect again and enter only the subdomain (e.g., yourcompany). Do not enter the full URL, do not include https://, and do not include .my.salesforce.com.
Complete the Salesforce authorization flow in the popup window.

Common Mistakes

What You Entered	Why It’s Wrong	What to Enter Instead
`https://acme.my.salesforce.com`	Full URL — Gumloop only needs the subdomain	`acme`
`acme.my.salesforce.com`	Includes the domain suffix	`acme`
`Acme Corp`	Company display name, not the Salesforce subdomain	`acme` (check your SF URL)
`acme.lightning.force.com`	Lightning URL format — use the `.my.salesforce.com` subdomain instead	`acme`

Still Need Help?

If you’ve confirmed the correct workspace name and still can’t connect, your Salesforce administrator may need to pre-authorize the Gumloop connected app first. See Salesforce Setup (Admin Only) in the docs for details, or contact support@gumloop.com.
