OpenVPN TLS Error after few hours of normal working

na flag

I'm connecting to remote device through VPN. I use OpenVPN Config: client

dev tun
proto udp
port *port*

remote *ip*

persist-key
persist-tun

<ca>
-----BEGIN CERTIFICATE-----
*cert*
-----END CERTIFICATE-----
</ca>

<cert>
-----BEGIN CERTIFICATE-----
*cert*
-----END CERTIFICATE-----
</cert>


<key>
-----BEGIN PRIVATE KEY-----
*key*
-----END PRIVATE KEY-----
</key>


cipher AES-256-CBC

tls-client
remote-cert-tls server
<tls-auth>
-----BEGIN OpenVPN Static key V1-----
*key*
-----END OpenVPN Static key V1-----
</tls-auth>

tun-mtu *value*
tun-mtu-extra *value*
mssfix *value*
auth-nocache

It works fine but after hours of work it shows:

TLS Error: local/remote TLS keys are out of sync: [AF_INET] *ip*
TLS Error: local/remote TLS keys are out of sync: [AF_INET] *ip*
...
TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
TLS Error: TLS handshake failed
TLS Error: Unroutable control packet received from [AF_INET] *ip*

How can I fix it? Thanks in advance.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
