Slack Issues Reports

Latest outage, problems and issue reports in social media:

  • BrettLudwig Brett Ludwig (@BrettLudwig) reported

    @SlackHQ Ubuntu 20.04 is crashing every time I join a slack voice chat. Is this a known issue?

  • PremiumFrye half whiskey half stuffing and half rage (@PremiumFrye) reported

    That'd be great if @SlackHQ worked one day this week. I mean, I'm not one to criticize not working much this week, but I'm not a critical infrastructure for hundreds of thousands of developers.

  • TheBiltong Logan (@TheBiltong) reported

    @SlackHQ managed to fix it with a shift - escape sequence :)

  • saifrahmed Saif Ahmed (@saifrahmed) reported from Arlington, Virginia

    @jugurthahadjar @SlackHQ @stewart Because it is the most obvious non-competitor. One could potentially see a threat to Slack from several other messaging platforms, but never, ever Skype — which is a threat mostly to itself. BTW, did they ever fix the can’t-login problems that caused the Skype-exodus?

  • israelscortio Fadare Israel (@israelscortio) reported

    @SlackHQ hey Slack, how can you help me look for a workspace? I got deactivated from my office workspace and I can't find it.

  • DomNicastro Dom Nicastro (@DomNicastro) reported

    @kellyjjrusk @SlackHQ For me, it was MORE of a distraction that it was down. I kept checking to see if it was back up! I would love to hear what companies did/will do next time when it/other collab tools go down.

  • zwaniga Andrew Zwaniga (@zwaniga) reported

    @SlackHQ @c_francis97 Has this been solved? This problem is occurring for me now across all of my workspaces. Very frustrating. But someone from the Slack help desk is patiently assisting me through email.

  • Vusys Bryan Channon (@Vusys) reported

    @SlackHQ @Ronef Bumped into this today. Weird and unnecessary limitation. Please fix.

  • jeffbarnum Jeff Barnum (@jeffbarnum) reported

    @SlackHQ Slack won't open on my Mac. Tried Help > Troubleshoot > Clear cache and exit; this does nothing. Please advise; thanks.

  • _amrita Amrita (@_amrita) reported

    Day 1: @SlackHQ is down Day 2: Jury Summons #juryduty ... I wonder what is in store for Day 3 ... the new year is turning out to be way more happening than the holidays

  • official4ten official4ten (@official4ten) reported

    @SlackHQ It's fixed. I don't know why but today the feature was activated for me without any issue. But thanks for your respond though

  • tdmalone Tim Malone (@tdmalone) reported

    @SlackHQ Hiya, just checking that the iPhone app bug where text is missing after a ``` code block is a known issue? I keep missing important things when it happens :(

  • PatchouliW Patchouli Woollahra nee Alia Fairbrooke (@PatchouliW) reported

    @mrbrown I shilled my boss on switching to @SlackHQ because I saw this coming. He laughed at the thought of paying for a free service. Who's laughing now?

  • parkerschmitt Parker Schmitt (@parkerschmitt) reported

    @SlackHQ Is it still down?

  • micahhenning Micah Henning 🧢 (@micahhenning) reported

    @hrbrmstr @SlackHQ I HATE the Slack login system. It’s the worst.

  • JacopoOttaviani Jacopo Ottaviani (@JacopoOttaviani) reported

    @SlackHQ @Jinukurian7 Any news on this bug fix? Experiencing the same issue here.

  • tbc0 tbc, the 0 is silent (aka Tim) (@tbc0) reported

    @adaptiveinsight I noticed my app server was unresponsive for several minutes. It's back now. Not worth filing a ticket. Just Twittering and wondering if any other Tweeps experienced the outage. Still a little sensitive to work stoppages after the @SlackHQ outage Monday. #htwoosh

  • bennop1 bennop (@bennop1) reported

    @SlackHQ I’m totally committed to bringing down the entire capitalist system. How can @slackHQ help me in my work?

  • DomNicastro Dom Nicastro (@DomNicastro) reported

    @kpodnar @SlackHQ When our Slack went down this week, I sent a light-hearted email to all-staff saying I've been marked safe from the Slack outage. But I kinda meant it. "Get me on email if you need me". It made me wonder about having something formal where all staff knows exactly where to go.

  • DeviceCoders Device Coders Inc. (@DeviceCoders) reported

    @SlackHQ To add insult to injury, we cannot even bookmark a slack channel because it just sends you to this idiotic login page! Grrrr!

  • Tyler_Potts_ Tyler Potts⚡ (@Tyler_Potts_) reported

    Can someone confirm if @SlackHQ is having constant server issues? All messages are delayed for like 5 - 10 minutes, sometimes I have to "resend" to get it to work? Been like this since it crashed on Monday...

  • payrovi2 Sam Payrovi (@payrovi2) reported

    @SlackHQ @Dave_Stein Hi @SlackHQ I'm having the same problem. It shows me the message (a URL actually) that failed to send when I hover over the exclamation point. But I can't find that message anywhere.... It must have been deleted if it was still a draft in the text box?? Anyway to remove this?

  • meeerakumar Meera Kumar (she/her) (@meeerakumar) reported

    @SlackHQ I'm still having trouble getting onto the desktop site, I can't even get this link to load. Please could you help? I deleted cookies and refreshed, but it's the only site I'm having an issue with

  • queene4theday QueenE (@queene4theday) reported

    Let me know when Pence and the Congress act right, Ossoff wins, and the Proud Boys burn down DC. I'm going to go back to work now, apparently, @SlackHQ has been up for 2 days now......I can't be OOO because tools ain't working.......

  • hrbrmstr boB "I can't fight 🏴‍☠️ w/o ☕️." Rudis (@hrbrmstr) reported

    Curse you, @SlackHQ, for your technical, abject incompetence that prompted me logging back into this $DEITY-forsaken platform this week. Of all weeks to be plugged back into socked-fueled IRL, it _had_ to be this one. Pls fire those tho caused the outage. #ty

  • RobinVerl Robin Verlangen (@RobinVerl) reported

    Slack down? :'( @SlackHQ

  • CodySalinas Cody Tate Salinas (@CodySalinas) reported

    @SlackHQ @Jdban Hey, Slack HQ! Do you know if this is still an issue? I uploaded a video I encoded in H.265 from Handbrake, and I experience the same issue (no video, only audio).

  • gcman105 Gary C (@gcman105) reported

    @SlackHQ I have been told by Slack support "there isn’t anything else that we can do to help" I simply want my email address changed!

  • cam_kaminski Music Dad (@cam_kaminski) reported

    @SlackHQ I use both but desktop is the one having the trouble mainly it seems!

  • siwander Siw Andersen (@siwander) reported

    So links on @SlackHQ won't open automatically but I have to COPY PASTE them onto Chrome. Help?
