Tawk.to has unexpectedly closed the connection [for some users in Vietnam]

Currently some of our users in Vietnam cannot use tawkto. When accessing, I encounter the following error.

www.tawk.to has unexpectedly closed the connection.

With chats embedded in the web, it also does not work. I wonder if tawkto is having problems. Please assist me.

Hi all, thank you for the feedback, and for your patience.

We are investigating the issue and will find a solution ASAP.

In the meantime, could you try accessing tawk.to using a VPN?

We know it’s not ideal, but it might be a temporary solution.

Through VPN we access https://www.tawk.to/ which works normally.

Dear Community,

We’ve identified that some of our users in Vietnam are facing difficulties accessing our services on tawk.to, specifically with DNS failures that prevent connection to our dashboard. This issue seems to be isolated to certain Internet Service Providers (ISPs) in Vietnam.

To better understand and resolve this matter, we’re asking for your help. If you’re currently in Vietnam and experiencing access issues, could you perform the following tests and share your results with us?

For Windows users:

  • Open PowerShell and run the following command:
    Resolve-DnsName -Name dashboard.tawk.to

For Mac OS/Linux users:

  • Open your terminal and run the following command:
    dig +trace dashboard.tawk.to

These tests will provide us with valuable information on the DNS resolution process from your location.

Additionally, as a temporary workaround, we suggest changing your DNS servers to one of the following public DNS services, which may improve your access:
Google DNS: and
Cloudflare DNS: and

You can find a guide on how to change your DNS settings here: What Is Google DNS? Changing Your DNS to

Lastly, we recommend contacting your ISP to report this issue, as it appears to be related to DNS resolutions on their end.

We understand the inconvenience this may cause and appreciate your cooperation and assistance in helping us diagnose and resolve this issue. Please send your test results and any other relevant information to support@tawk.to.

Thank you for your support and patience.

Kristaps and the team at tawk.to
