I am unable to send any email via SMTP. I have a working instance other than that, it seems that way so far anyway. I get this error from the admin panel and from the send validation email when you log into the vault. I have tried Google, M$ and my own SMTP information, which I have confirmed all working. [2020-06-11 19:23:04][bitwarden\_rs::api::identity][ERROR] Error sending new device email: SmtpError. [CAUSE] Io( Os { code: 11, kind: WouldBlock, message: “Resource temporarily unavailable”, }, ) I have no other warnings or errors in the logs. Any ideas or need any additional info from me?

I can’t see why this would bother anything… ---

It looks like the smtp server is not reachable with the parameters given. Please check if the host and port are correct. ---

Thanks for the reply. No matter what I place in the admin settings this is the error: > [2020-06-16 15:01:57][error][ERROR] SmtpError., > [CAUSE] Io(, > Os {, > code: 11, > kind: WouldBlock, > message: “Resource temporarily unavailable”, > }, > ), > [2020-06-16 15:01:57][response][INFO] POST /admin/test/smtp (test\_smtp) =\> 400 Bad Request, I have many other apps working from the same server, all using the same SMTP credentials. Any advice? ---

Is DNS working? You could check the diagnostics page in the /admin interface. Also, try to increase the `smtp_timeout` from the default 15 to 30 or 60 even and see what happens then. ---

Please see screenies below. Still failed at 60. I assume diag page is OK. ![bw-diag-page](https://global.discourse-cdn.com/free1/uploads/vaultwarden/original/1X/04c5f71ca1cfebfcc7d537cc3310cb4aad7b9ab4.png) ![bw-smtp-settings](https://global.discourse-cdn.com/free1/uploads/vaultwarden/original/1X/b0ad9128064853a2727b437db5d415e2770e83b3.png) ---

Just to be sure, you did do a save of the settings when you changed the timeout to 60 before you tried the test again right? If so, was the error message still the same? ---

😆 Upon your first reply, when I tested again this morning, I thought I was forgetting to click save each time, turns out I was indeed clicking save this time and the prior times. Anyway, yes, the same error. It doesn’t seem to matter what I put in there, just the same error over and over with working / non-working SMTP credentials. All I know for sure is, it is specific to this container. I was hoping there would be lots of other info on the forums/github but alas, it seems to be me. I just wish there was a better error message to go off of. ---

Follow Up Here: Outlook SMTP working GMAIL SMTP working Personal SMTP not working - I have no idea why not. It works on all my other apps. Anyway, I’m just happy one of them is working. Maybe it was an update, maybe I am fried. WHO knows! ---
