Question: I had been working on Colab using: from google.colab import drive .mount('/content/gdrive')  with no problems, until today. I don't know why this error was raised: Go to this URL in a browser: https://accounts.google.com/o/oauth2/auth?client_id=947318989803-6bn6qk8qdgf4n4g3pfee6491hc0brc4i.apps.googleusercontent.com&redirect_uri=urn%3aietf%3awg%3aoauth%3a2.0%3aoob&scope=email%20https%3a%2f%2fwww.googleapis.com%2fauth%2fdocs.test%20https%3a%2f%2fwww.googleapis.com%2fauth%2fdrive%20https%3a%2f%2fwww.googleapis.com%2fauth%2fdrive.photos.readonly%20https%3a%2f%2fwww.googleapis.com%2fauth%2fpeopleapi.readonly&response_type=code Enter your authorization code: ·········· --------------------------------------------------------------------------- TIMEOUT Traceback (most recent call last) <ipython-input-4-d05fe204dd76> in <module>() 1 from google.colab import drive ----> 2 drive.mount('/content/gdrive') 4 frames /usr/local/lib/python3.6/dist-packages/google/colab/drive.py in mount(mountpoint, force_remount, timeout_ms, use_metadata_server) 223 oauth_prompt, 224 problem_and_stopped, --> 225 drive_exited, 226 ]) 227 if case == 0: /usr/local/lib/python3.6/dist-packages/pexpect/spawnbase.py in expect(self, pattern, timeout, searchwindowsize, async_, **kw) 342 compiled_pattern_list = self.compile_pattern_list(pattern) 343 return self.expect_list(compiled_pattern_list, --> 344 timeout, searchwindowsize, async_) 345 346 def expect_list(self, pattern_list, timeout=-1, searchwindowsize=-1, /usr/local/lib/python3.6/dist-packages/pexpect/spawnbase.py in expect_list(self, pattern_list, timeout, searchwindowsize, async_, **kw) 370 return expect_async(exp, timeout) 371 else: --> 372 return exp.expect_loop(timeout) 373 374 def expect_exact(self, pattern_list, timeout=-1, searchwindowsize=-1, /usr/local/lib/python3.6/dist-packages/pexpect/expect.py in expect_loop(self, timeout) 179 return self.eof(e) 180 except TIMEOUT as e: --> 181 return self.timeout(e) 182 except: 183 self.errored() /usr/local/lib/python3.6/dist-packages/pexpect/expect.py in timeout(self, err) 142 exc = TIMEOUT(msg) 143 exc.__cause__ = None #

I have been working for a long time importing files located on my Google drive and never had these problems.

Answer: It turns out that if you manually copy the auth code from the auth button instead of clicking the copy button, it works
