404 in a number of conf files.

Hello,

Looking for some help. We've noticed something odd happening accross our DA deployed servers over the last few days where a number of config files have the following at the top of the files:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>404 Not Found</title> </head><body> <h1>Not Found</h1> <p>The requested URL was not found on this server.</p> <p>Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.</p> </body></html>
To fix the affected service, we just removed the code and then went hunting for its source, which we've been unable to do so. We believe it's coming from the updater but as to why (bar the possibility that the file the updater is looking for has moved), we're unsure.

Diving into the files, we found that updates look to come from "files.directadmin.com" so we made sure that was accessible from the server and not blocked by the firewall or remotely, which it wasn't.

PING files.directadmin.com (104.128.54.74) 56(84) bytes of data. 64 bytes from files.directadmin.com (104.128.54.74): icmp_seq=1 ttl=54 time=74.8 ms 64 bytes from files.directadmin.com (104.128.54.74): icmp_seq=2 ttl=54 time=75.2 ms 64 bytes from files.directadmin.com (104.128.54.74): icmp_seq=3 ttl=54 time=75.1 ms 64 bytes from files.directadmin.com (104.128.54.74): icmp_seq=4 ttl=54 time=75.0 ms 64 bytes from files.directadmin.com (104.128.54.74): icmp_seq=5 ttl=54 time=116 ms 64 bytes from files.directadmin.com (104.128.54.74): icmp_seq=6 ttl=54 time=74.8 ms --- files.directadmin.com ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5008ms rtt min/avg/max/mdev = 74.800/81.916/116.295/15.377 ms
(same for the multitude of other ips files. can come from, and tested with the firewall off to be 100% certain). We also set a hosts edit on the server to ensure "files.directadmin.com" was only checking a known working mirror to no effect.

Deciding that the issue must be the updater, we ran "./custombuild/build versions" and got the following:

/scripts/da/build: eval: line 3517: syntax error near unexpected token `<' /scripts/da/build: eval: line 3517: `VERSIONS_TXT_<!DOCTYPE HTML PUBLIC "_//IETF//DTD HTML 2_0//EN">= VERSIONS_TXT_<html><head>= VERSIONS_TXT_<title>404 Not Found</title>= VERSIONS_TXT_</head><body>= VERSIONS_TXT_<h1>Not Found</h1>= VERSIONS_TXT_<p>The requested URL was not found on this server_</p>= VERSIONS_TXT_<p>Additionally, a 404 Not Found= VERSIONS_TXT_error was encountered while trying to use an ErrorDocument to handle the request_</p>= VERSIONS_TXT_</body></html>='
(Removing versions.txt first results in the same, only a download first with the same inside versions.txt)

DirectAdmin appears to be running v1.63.3
Version: DirectAdmin v.1.63.3
And error logs (/var/log/directadmin/{error,errortaskq,system}.log) are clear.

Not really sure where to go from here. Any help would be appreciated.

As mentioned in the ticket, files5 is an unofficial mirror, it did not have this file there.
 
Code: 
cd /usr/local/directadmin/custombuild
./build set_fastest
./build update
 
I opened this post prior to opening a ticket because I was under the (wrong) impression at the time that our licenses had direct support. I found out 4 hours later (this post was in an approval queue during that time) that wasn't the case and quickly moved it to a support ticket, but couldn't close this myself. So apologies @smtalk for that.

For anyone else that encounters this, the fix:
edit "/usr/local/directadmin/custombuild/options.conf"
Find "downloadserver=" under "#CustomBuild Settings"
Change from "files.directadmin.com" to "files-de.directadmin.com"
Save and close.
rm -f "/usr/local/directadmin/custombuild/versions.txt"
/usr/local/directadmin/custombuild/build versions

It may (we had already done so prior to the fix) still be necessary to remove the 404 junk from the various config files prior to the fix.

The server above specifically was set to use files5.directadmin.com, not files. though we have no idea how that occurred, other servers using files.directadmin.com also had this issue.

Thanks.
