Is Plusnet email down.

pittdj70 — Thu, 26 Feb 2026 10:26:33 GMT

Plusnet email, not Greenby, is down here.

Connections to the server “imap.plus.net” on the default ports timed out.

Plusnet webmail is also down.

N.B. I have not yet been moved to Greenby.

Or do both Greenby and Plusnet email provisions use the same server names?

There is another post about Greenby not working.

@Townman @plusnettony

Trying to reach webmail.plus.net is giving me (in Firefox latest version):

Secure Connection Failed

An error occurred during a connection to webmail.plus.net. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the web site owners to inform them of this problem.

which often means the site certificate is invalid.

Please can this be addressed as a mater of urgency.

Thank you.

Using MS Outlook every Plusnet POP3 connection has failed reporting the "Encryption Type" is not supported.
SSL/TLS was working fine yesterday.

Thunderbird IMAP connection to Plusnet is failing to connect.
This was also working yesterday.

It all stopped working for me about an hour ago.

Please note, this problem is also being discussed in this topic:

https://community.plus.net/t5/Email/Is-Greenby-down-again-26th-Feb/td-p/2038665

It seems that 'they' have broken the secure access protocols.

EDITED TO ADD:

Perhaps a mod. should merge these two topics @Baldrick1 ?

@plusnettony I've got the same issue. None of my mailboxes are connecting from my (POP) email client. And I can't even get the plusnet OR Greennby webmail pages to load.

This may be a separate issue but late last night I logged on to mail (on my Mac) and it started (re)-downloading every email in 3 of my mailboxes. ie over a thousand of them in total. This is what happened when we were initially migrated: emails that had been moved from my inbox (on mail client) reappeared and those that were still there were marked as unread. Really a pain to have to go through everything again.

Me too. I was able to collect Plusnet email on my phone earlier this morning, but getting it on my computer just now I got the message 'everyone' is getting. Non-Plusnet email is coming in OK as usual.

Thanks for letting us know - We raised it this morning and our suppliers are investigating.

Indeed. Currently the Plusnet Squirrel Webmail site can't even be reached.

Hmmm… can't reach this page

It looks like webmail.plus.net closed the connection

I have the same issue - no access to webmail via Firefox, Chrome or Edge. Thank you for raising the issue. Please keep us advised on when the service should be restored.

I was preparing the following post:

I have just detected that Plusnet email accounts may not be synchronising.
On an existing setup account:
Using full email address, mailbox password, IMAP.plus.net, port 993, SSL/TLS security.
This now throws the error "Email security not guaranteed, ...the highest security level may not be supported"
Changing security to "None" doesn't succeed either.
This results in not being able to add the address to an email client.

No access for me to webmail.plus.net or IMAP using MacOS Mail or Windows Thunderbird

I'm not yet migrated to Greenby

Re: Is Plusnet email down.

BCN — Thu, 26 Feb 2026 11:26:54 GMT

Both Plusnet and Greenby email are down here. On both I get the following immediately on opening the page (no way to even try to log in to see emails):

Hmmm… can't reach this page

It looks like webmail.greenby.com closed the connection.

Try:

Checking the connection
Checking the proxy and the firewall

ERR_CONNECTION_CLOSED

IanEdmundson — Thu, 26 Feb 2026 11:28:25 GMT

"The connection was intentionally closed by the server befopre the session was completed."

AND the plusnet webmail page doesn't connect.

This site can’t be reached

webmail.plus.net unexpectedly closed the connection.

Try:

Checking the connection
Checking the proxy and the firewall
Running Windows Network Diagnostics

ERR_CONNECTION_CLOSED

This is showing as fixed but it is not fixed for me, still cannot access mail via webmail or client email.
