Often, problems related to DNS result in improbable error messages in web browsers. E.g. web browser claims that
www.google.com does not exist:
If your web browser reports that a website does not exist while it works while using different Internet connection (e.g. when using mobile Internet connection), follow this guide.
On the other hand, it is unlikely that you have a DNS problem if the page loads but reports some other error, e.g.
503 Server Unavailable:
This guide will likely not help you in such cases.
Before you touch router configuration in an attempt to self-fix the problem it is necessary to gather data about the problem and send them to support. The data are necessary for detailed diagnostics and will allow us to improve software so the problem does not happen again either to you nor other users.
First of all, the data gathering process must be started before the problem manifests. This is the first step you have to do because the verbose logging is not enabled by default for performance and privacy reasons.
Package for debugging resolver isn't the standard part of TurrisOS system, because of that it's necessary to install it from our repository before debugging.
If the problem occurs only occasionally, it is better to enable verbose logging now and wait. It would be too late to enable verbose logging after the problem occurred.
After enabling verbose logging, it is necessary to time visit the site which manifests the problem from time to time. If the site still works you have to wait longer. When the site stops working continue with next step, where you will download verbose logs.
When the site stopped working download verbose logs using this process.
