Resolved Backup broken since update to 18.0.50 (when using FTPS+"active mode")

[lj-shadow]

Server operating system version

Ubuntu 22.04.1 LTS

Plesk version and microupdate number

18.0.50

Hello,
Since the update to 18.0.50, the backups to the FTP server no longer work.
Under "Tools & Settings -> Backup Manager" I only get a white page with endless loading.
So this setting isn't available/usable anymore.

The daily task for incremental backup (to FTP only) runs in an timeout but the hint to check it via cli by

" curl -v -P - --ssl -k -u USERNAME 'URL' "

works like a charm.
What can I do?

 

[TomBoB]

Same here. On all our servers.

I do apologize up front, but

EVERY ... SINGLE .... TIME ... Plesk changes something to with [FTP] backups, THEY ... F**K ... IT UP !!!!

We've been using Plesk since version 8 (!). Backups, ... EVERY SINGLE TIME!!
I really really have to hold back not to plaster this post with swearwords...

 

[Peter Debik]

Could you please check into /var/log/plesk/PMM/backup-2023-MM-DD-HH-ii-... of the hanging backup? Do you see any error messages in the pmmcli.log or backup.log files?

 

[TomBoB]

Hi Peter,

the pmmli.log shows no errors at all.
the backup.log shows:

I don not believe that the transport error is the main reason. We have had that on rare occasions in the past, but was never anything to worry about.

When you go Settings&Tools, Tools&Resources, Backup Manager, it never opens the page that's supposed to be displayed. The just sits there waiting for a response. It like its waiting for input that never comes.

 

[TomBoB]

Forgot the mention, all servers are on Almalinux 8, latest update. In case that helps narrow it down.

Noticed the Extension "Scheduled Backups List" bug. Can now access that, however clicking on Backup Manager in the breadcrumbs has the page loading endlessly again.

 

[Peter Debik]

@lj-shadow Are you with Hetzner Storage Box, too?

 

[Peter Debik]

@TomBoB Thank you for the details. I went ahead and created a ticket for developers to check into the issue. In case you have questions on this case to support staff, please refer to ID [PPS-13913]. I'll have an eye on it, too.

 

[Peter Debik]

Support engineers are asking for more information:
1) Please enable "Debug mode" as described in https://support.plesk.com/hc/en-us/articles/213373669. Please make sure that "FORCE_DEBUG_LOG 1" is set as described in the "For Scheduled Backup Tasks" section.
2) Then let the scheduled backup run and also, please run backup manually.
3) Please provide all logs generated from this (/var/log/plesk/PMM/backup-**/). I suggest sending them in a private message to me, not to expose the details publicly here on the forum.

 

[TomBoB]

Hi,

can't access the GUI page [still loads endlessly] to run the manual and scheduled backups.

From CLI I get after a few seconds:

plesk bin pleskbackup --server -ftp-server xyz.your-storagebox.de -ftp-login 123loginuser -ftp-password 123pw

The backup failed with errors!
exit status 255

Will send logs shortly.

 

[TomBoB]

Figured it out.

Log into your servers, go straight to path

https://serverx.yourcompanycom/admin/backup/ftp-settings/

untick "Use FTPS"

Save.

Working again.

I feel I may have to apologize to Plesk. It may after all not have been caused by a Plesk update issue but by curious coincidence with Hetzner doing something their side.
Still would be nice to get backups to FTP using FTPS going again. Plus Plesk detecting the non-connection / timeout when opening the Backup Manager, instead of just sitting there until an eventual timeout occurs and a 503 bad gateway is displayed.

tested above on 3 servers so far and the "workaround" did the trick on all.

 

[Peter Debik]

Thank you for the update. Good to have a workaround, but FTP without encryption cannot be a final solution. We'll keep checking this for sure. It must also work with FTPS.

@TomBoB Ever thought of using sshfs to mount the storagebox directly on your server? That way, you can skip the FTP part and create backups to something like: /mnt/storagebox

@maartenv Yes we did look into that a long while back, but it wan't feasible for us for multiple reasons. But will definitely look into that again! Thanks!

Hello...

thanks for your reply.

Can confirm: untik "use FTPS" as workaround seems to work.
New Backup is running atm and i'm waiting if it fails.

I'm at Strato

@lj-shadow, @TomBoB could one or both of you please open a ticket with Plesk support and allow SSH access to your server(s) for support? Developers would like to check the issue directly on the server, because we were yet not able to determine the cause. It does not seem to occur everywhere.

I think so, too. For the time being please use the free trial period.
Thank you for opening the ticket.

I don't have an licence from plesk directly - it's a strato licence. I don't know if i can open a ticket then.

 

[Maarten.]

You can get support from Plesk directly, even if your license is from Strato.

It's a subscription, but it's free for the first month:

Developers were able to reproduce the issue under the condition that "Passive Mode" is turned off. The product issue has been confirmed and will now be tracked with ID [PPPM-13895], [PPP-60041]. According to developers, the workaround when using FTPS is to also check "passive mode".
