What steps will reproduce the problem?
1. VirtualHost "foo_bar" in config
2. prosodyctl cert generate foo_bar
What is the expected output?
No unhandled error / traceback. Probably a rejection of the illegal hostname from somewhere.
What do you see instead?
lua: ./prosodyctl:635: ./util/openssl.lua:109: attempt to concatenate a nil value
stack traceback:
./util/openssl.lua:109: in method 'add_sRVName'
./util/openssl.lua:128: in method 'from_prosody'
./util/prosodyctl/cert.lua:46: in field 'config'
./util/prosodyctl/cert.lua:143: in function <./util/prosodyctl/cert.lua:136>
(...tail calls...)
./prosodyctl:751: in upvalue 'func'
./util/async.lua:144: in function <./util/async.lua:142>
stack traceback:
[C]: in function 'error'
./prosodyctl:635: in local 'handler'
./util/async.lua:232: in method 'run'
./prosodyctl:754: in main chunk
[C]: in ?
What version of the product are you using?

Please provide any additional information below.
Underscore (_) is illegal in hostnames and thus in certificates, and the IDNA to_ascii() operation rejects this, the resulting nil goes into a concatenation.
