That “Network error” is incredibly frustrating, but it’s almost always a browser issue rather than a problem with your actual network. The most effective first step is to open a new incognito or private browser window and try connecting your TikTok account there. At the same time, you must temporarily disable any ad blocker or VPN extensions, as they are a primary cause of this specific login problem because they interfere with the authentication scripts.
If that doesn’t work, the next step is to confirm there isn’t an issue with your TikTok account itself. Try logging in directly on the TikTok Ads Manager website. If you can log in, then the final troubleshooting step is to perform a clean reset of the connection. In your Shopify admin, completely uninstall the TikTok sales channel, and then reinstall it from the App Store. This forces a fresh setup and usually resolves any persistent connection errors.
Hey there, you can check for the following things:
Is a VPN active?
Can you try using another country in your VPN?
Is the TikTok server functioning? Check the downdetector.
Is the issue from your network?
Is the issue coming from the account.
The best thing to do is reach a TikTok support executive. Ask them if there is something wrong from there end. If there is an issue from your end, check VPN or restart your internet/wifi.
