Selenium/ChromeDriver Timeout Exception when Webscraping

Question

I have built a webscraper that scrapes urls. Its occassionally having an issue (doesn't occur all the time). I get a TimeOutException at this particular part of my code:

tries = 0
while tries<1000:
    try:  
        domain=wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, "cite._Rm")))
        domain = domain.text
        break
        except StaleElementReferenceException:
            tries+=1
            self.browser.refresh()

Error:

File "", line 389, in findDomains domain=wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, "cite._Rm"))) File "", line 78, in until raise TimeoutException(message, screen, stacktrace) TimeoutException: Message:

The code you show in your question won't run.

Since you have it wrapped in a while block with multiple attempts, just handle TimeoutException:

try:  
    domain=wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, "cite._Rm")))
    domain = domain.text
    break
except (StaleElementReferenceException, TimeoutException):
    tries+=1
    self.browser.refresh()

Note that it's difficult to say more without being able to reproduce the problem, or at least having a link to the target webpage that have occasional issues you are describing.

You get timeout exception because element was not found during timeout, try to increase it or refresh page like in a code below

tries = 0
while tries<1000:
    try:  
        domain=WebdriverWait(self.browser, timeout=10).until(
             EC.presence_of_element_located((By.CSS_SELECTOR, "cite._Rm"))
        )
        domain_text = domain.text
        break
    except TimeoutException:
        tries+=1
        self.browser.refresh()
