Kyocera SMTP error - SSL/TLS - stopped working

[stroltz]

We have multiple ECOSYS M6530cdn printers - send email has stopped working using SSL/TLS ( Connection Error (0x4803)
We have a single newer ECOSYS M6230cidn - and the send email still works just fine with SSL/TLS. Is on the same network as a broken one.
I can't see any difference in the relevant settings between the new and old machines.

The mail server is a cpanel hosted webserver. version 88.0.10 Nothing much special about it as far as I can tell.

The old M6530cdn will work if I switch to no SSL but we want to use SSL.
I have tried generating a new security certificate.
Switching off SSL3.0/TLS1.0 and TLS1.1
Using the IP of the sever instead of the name.

I can't find any firmware files to download for the M6530cdn

Does anyone please have any ideas?

my guess is that an update on the server has broken the SSL/TLS for the older version used by the older machines. I hope there is a way to get it to work?

I think you will need newer firmware on troubled machines.

Thanks.
That is what I suspected.
I have asked Kyocera. There does not seem to be a way for me to access the firmware download.

Here are the numbers of the firmware the M6530cdn has installed, that no longer work.

System : 2NW_2000.003.204
Engine : 2PC_1000.001.107
FAX : 2NM_5100.006.009

I have been told there is a firmware update available;
M6530cdn_7.113_4.005

but of course it costs a fee to have someone come out; and there is no guarantee that a new firmware will fix the problem.
I wish I could download the file somehow.....

You have updated I/S on your server, pay for Kyocera to fix it then send the bill to Microsoft for breaking your machines. LOL.

In case anyone has the same problem.
The new firmware 7.4.0030 fixed the issue.
I got it from Firmware Update - Printer & Copier Firmware - so had to pay - but a lot cheaper than a service call from Kyocera.

Happy to help, glad this resolved your issue.

When you use an old browser or operating system you will encounter err_ssl_version_or_cipher_mismatch error . You might even face a variant of this error message .
It happens mainly because the browser does not trust the SSL certificate and there are many ways that you can check to fix the error .
