hi

would you please try to modify /config/openvpn/keys/ta.key 1 to /config/openvpn/keys/ta.key and test again

then please check if the signature of the certificate is md5 or sha1?

W52P doesn't support SHA256, it should use SHA1 or MD5, please chaange it and then recreate the keys, you can change it in "openssl.cnf" file , change sentence :

"default_md = sha256"

change to :

"default_md = md5"

"openssl.cnf" file in windows: Open VPN --- easy-rsa --- the file begin with openssl, it may be openssl-1.1.1.cnf or some like this
"openssl.cnf" file in linux: easy-rsa or the subdirectories under it ,also begin with openssl

I have uploaded a sample Openvpn file(Openvpn_sample.tar) for your reference, please follow this format to create the .tar file.

Thank you!

Best Regards,
Michael

@Yealink_Michael:

is that limitation to SHA1 and MD5 hardware related or is it possible to support SHA256 in future firmwares of the W52P?
Would that also affect SIP/TLS certificates?

Next year many internet services will switch to SHA256 and deprecate SHA1.

@Yealink_Michael:

Here is more information about the SHA-1 deprecation :
https://blog.cloudflare.com/sha-1-deprec...ft-behind/

Would auto-provisioning via https still work with SHA-256 certificates with the W52P?
Do other Yealink models (firmwares) also have this limitation to SHA1 and MD5?

Install the firmware for the w56p base station (compatible with the w52p base station) it is fixed there:
