"Error connecting to server" in Firefox 46

huubsanders

When syncing, zotero stops and reports 'cannot connect to server'. ID 1562419168.
My other applicatrions work, there is internet connection. I have the latest versions of zotero and firefox installed.

Provided you're using Firefox 46, there does seem to be an issue for some people, but so far, Zotero devs haven't been able to replicate it (and so they don't know what's causing it). They're looking for Debug IDs for failed syncs (different from report IDs):
https://www.zotero.org/support/debug_output [Edit: See below.]

Debug ID is D1715999346.

Debug ID is D2036462764.

If this is still happening for you, if you could go to the URL about:support in the Firefox address bar, click the "Copy text to clipboard" button, paste the text into an email, and send it to support@zotero.org with a link to this thread, that would be helpful. We're trying to figure out what's different on the systems where this is occurring.

Note that this seems to occur only for uploads, so if it seems to be working, make a local change to an item and then make sure you can sync successfully after that.

Additional information that may be helpful. If I restart my computer (OS X) I can usually connect to the server one time. Subsequent sync processes fail.

Hi, I've been getting sync problems too.
Windows 7, Firefox 46
report id : 426179202

The first time this happened, restarting Firefox helped, this time it didn't. Let me know if I can help more. I'll check on my linux mint install, see if that behaves.

this one after disabling all other extensions and closing all other tabs. Weirdly, it will let me 'verify server' in the sync preferences, and then comes up with the "Error connecting to server. Check your Internet connection." when I try to sync

I got also Sync-problems after syncing my old profile:

Report-ID: 1619492208

I tried to sync an existing profile, without success. Progressbar showed syncing-process, but I had no added entries in the online-store. My local machine got also no updates from my online-store.

According to the following discussion-link, I created a new FF-profile, copied my old Zotero-content into the new Zotero-folder and then I got at least new entries in the online-store and on my local machine. But attachments are not syncing and error-warning is still shown.

I have been trying to sync since yesterday(april 29th) and all attempts ended with:
"Error connecting to server. Check your Internet connection."

I had added some new entries with attachments on my local Zotero and I saw that some did arrived on the Zotero on-line server, but not the last ones.

Synchronisation seems to work again: you can close Report ID : 1500834462

(@Dan -- have you been getting enough of the about:support dumps or should we still be encouraging people to do that?)

Same error here. Just installed latest Firefox and Zotero on Mac OS X 10.10.5.

There are 3 IDs generated by the error:

Let me know if you need more about:config logs.

If there's someone experiencing this who's comfortable performing advanced troubleshooting (running code in the Firefox dev tools, installing alternative Firefox builds, etc.), could you email us at support@zotero.org? This seems to be some sort of bug in Firefox 46, but we've never seen anything like this, and we're going to have to do some lower-level troubleshooting to be able to report it to Mozilla or work around it.

For everyone else, I would recommend installing Zotero Standalone (if you don't have it already) and syncing with that for the time being. Note that, if you haven't used Standalone before, it will ask to share your existing data directory when you first start it, and you should say yes.

We don't need any further Report IDs or about:support output at this time, but keep an eye on this thread for updates in case we need further information. You can subscribe to the thread in the left sidebar. (Note that you'll only receive one email notification after each time you visit the forums.)

Just confirming that downgrading Firefox to v45.0.2 solves this problem.

Cannot Sync. Recently I have added few links and other resources but cannot link. Always showing red ! sign. I have reported. Report ID: 591298593.
Please let me know how to Sync because I need to add those links and resources with my paper.

dstillman

OK, thanks to some great help from the dev list we may be close to identifying the problem here.

It'd be great if we could get network logs from a few people experiencing this. Steps are here:

https://developer.mozilla.org/en-US/docs/Mozilla/Debugging/HTTP_logging

If the steps don't make sense to you, you can ignore this.

If you're comfortable running them, you should trigger the sync error immediately after starting Firefox this way (before loading other webpages) and then quit Firefox and restart Firefox normally to stop the logging. You can then open the log in a text editor, X out any passwords, resave it, and email it to support@zotero.org.

Have the same problem!
Report ID 143813307
After log generation Report ID 1478113858
I have emailed the log following your instructions. Hope you can help!

OK, a proper fix is coming from Mozilla — reverting a change in Firefox 46 — but we've made a temporary server-side change that will hopefully fix this for most people immediately. You might see intermittent errors until it's fixed in Firefox. Let us know if you're still having trouble.

Thanks to everyone for their help debugging this, and our apologies for the inconvenience.

Now syncing with your temporary server-side fix.
Thank you !

rewa

the error message has disappeared now, everything seems normal again. thanks!

boombuia

Thanks for the update and temporary fix. I had started getting the errors (again) and was using standalone. Firefox 46 is now syncing (up&down) again.

dstillman

Standalone isn't affected by this, so that wouldn't be the same issue. Closing this now.
