Solve the problem of "DNS problem: NXDOMAIN looking…\\" in OneinStack

Currently, in the one-click WEB environment of Linux in mainland China, LNMP and OneinStack are most commonly used. Whether it is in terms of function or operation, it is relatively easy to use, and if you encounter problems, you can basically find solutions or ask the author to solve them. A few days ago, Snail installed OneinStack on one of the company's servers and found that there had been new changes. For example, the original Let\\’s Encrypt certificate was installed separately as an extension, but now it is created directly when adding a site.

However, there was a problem when configuring the Let\\’s Encrypt SSL certificate for the site\\"Let\\’s Encrypt Verify error! DNS problem: NXDOMAIN looking up A for...\\". And based on the \\"Solution\\\'s Encrypt\\" DNS problem: NXDOMAIN looking up A..\\"Configuration problem\\" solution that Snail encountered before, it does not solve this problem. It should not be parsed. The problem.

So I consulted the author yeho and was told that I needed to upgrade OneinStack and then try again.

1. Upgrade OneinStack

cd oneinstack

sh upgrade.sh oneinstack

2. Install SSL on the normally added site

You can install the certificate after the upgrade, at least this problem is solved. If we encounter such a problem, we can follow suit and solve it. If we are worried about the problem, we can back up the data first.
