DNS auth creates TXT record with "value=" prepended to the payload causing validation failure.

[lifeboy]

I use the following command to attempt to issue a certificate.

/root/.acme.sh/acme.sh --issue -d poc.fast.za.net --post-hook "/root/restart-after-cert-update.sh" --server letsencrypt_test --staging --test --force --dns dns_miab --dnssleep 300

The output shows this:

[Mon Dec 8 15:07:40 SAST 2025] Using CA: https://acme-staging-v02.api.letsencrypt.org/directory

However, then I check the record that was created. I see this:

; ANSWER SECTION: _acme-challenge.poc.fast.za.net. 43200 IN TXT "value=5OJ_vQicbfid4_tEhPfiouTpg1vpRANB_N-MAQ2o6hs"

I have been testing a lot with this dns validation process and out of the blue it seems (same server, same domain, same DNS server (MIAB)), I get the "value=" prepended.

What's going on here?

Please upgrade to the latest code and try again first. Maybe it's already fixed. acme.sh --upgrade If it's still not working, please provide the log with --debug 2, otherwise, nobody can help you.
