Error code: ssl_error_no_cypher_overlap

my gmail account has started throwing up the message,

"An error occurred during a connection to pop.gmail.com:995"

"Cannot communicate securely with peer: no common encryption
algorithm(s)."

"(Error code: ssl_error_no_cypher_overlap)"

I've tried deleting Google certificates in the hope that the email
client (Eudora OSE) might reload them, but this approach has not yet
worked.

This has just started happening recently.

Help, please?

"There is security software like Avast and Kaspersky

* BitDefender - Privacy settings - disable Scan SSL "

Did you make a change to your AV product lately ?

I use Kaspersky AV. I just tried the following in Kaspersky;

click "settings", bottom LH corner

click "additional"

click "network"

click "monitor selected ports only", and uncheck "995" (inactive)

click "do not scan encrypted connections"

close the Kaspersky window

Curiiously, Eudora OSE now works with these settings. I'm unsure as to
whether making these changes has caused Eudora to work.

I'm still getting the problem. I unloaded (exited) Kaspersky, and the
same error message still happens, every time I try to check mail. I
cannot download email because of this error.

Help, please?

"Eudora OSE msg error

I use POP connection with server with this settings:
pop.gmail.com
port 995
connection security SSL/TLS
secure authentication disabled
"

"I deleted all the certificate of GOOGLE i've found in
EUDORA and now all works fine !"

In this later one, no amount of tinkering would fix it.

On the older Eudora, they do a lot of fiddling with it too.

And I don't know if Google will allow a connection
on other than port 995.

If it was a certificate error, I would have expected to see a different
error message.

FYI Gmail dropped support for SSLv3 earlier this year.
https://gsuiteupdates.googleblog.com...d-rc4-for.html
Now the minimum cryptographic protocol which Gmail supports is TLS1.0

However, I would assume Eudora OSE does support TLS1.0. But if your
Eudora OSE did not support TLS1.0 or higher, then you would not be
able to connect to Gmail.


One suggestion to try out is using STunnel to provide the SSL/TLS
encryption to Gmail
