hmm is the problematic line a bug in mod_md status output?

I tried with compiling the latest v2.4.28 from https://github.com/icing/mod_md/releases but I get the same output. Perhaps I should submit a bug report there instead.

Thank you very much. I have modified the plugin to be more tolerant.

ManagedDomain[0]: onManagedDomain[0]CheckAtType: rsa

Yes, this is exactly the problem (the plugin expected a "key: value" pair).

[wwuck]

Thanks for the fix. Upstream has also fixed the problem there.
