Nginx location regex is not matching
Solution 1:
I would try it without the brackets around \d, brackets are normally used for either contiguous characters or numbers, your brackets say match either character '\' or 'd'
"^(.*)(\d{10})\.(min\.)?(css|js)$"
Also, are you specifically saving the group info that you're capturing inside the parens?
For clarity on the comments below.
Start simple.
"^.*[0-9]*\.css$"
"^.*[:digit:]*\.css$"
"^.*\d*\.css$"
Depending on which works, use that base for the digits and expand as below.
"^.*\d{10}\.(min\.)?(css|js)$"
If you're matching the http/https as well, you can start it with the http/s stuff below, remember to change to which ever digit notation worked.
"^http(s)?://.*[0-9]{10}\.(min\.)?(css|js)$"
