Single Byte XOR Cipher

I am supposed to decode this string: IConIT0xdSoldit1GTJ2GTIudRkxdigidTQgMyoZMXY0KiIZdiAZJTQ/NjJ2Zzs=

I first recognize that this is in base64 format, so i decode it to hex and get 202a27213d31752a25762b7519327619322e751931762822753420332a193176342a221976201925343f363276673b. Then I tried using this solution to decipher the text but it isn't working. I've been stumped for days trying to figure this out. Can anyone provide me with a clue as how to proceed with this?

You're on the right track. The decrypted string has some unusual properties, and you're unlikely to be able to detect it with frequency analysis. You can narrow down the possibilities a little by considering the range that the XORed characters will end up in, but the easiest approach will be to just try them all and print the results.

The correct XOR key is between 0x40 and 0x5f.
