Getting this Error: json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

[MaximilianPannenbaecker]

Hallo I am keep getting an Error for different scripts her an exampl script:
`tickers = gettickers('mdax')
days = 30
returns, symbols = [], []
klines = {}
for ticker in tickers[]:
klines[ticker] = yf.download(ticker.upper(), interval='1d', period=f'{days}d', threads=False)
if len(klines[ticker]) > 0:
cumret = (pd.DataFrame(klines[ticker])['Close'].astype(float).pct_change() + 1).prod() - 1
returns.append(cumret)
symbols.append(ticker)

retdf = pd.DataFrame(returns, index=symbols, columns=['Return'])`
print(retdf.Return.nlargest(3))

I am getting an Error thrown for different stocks each time. Did yahoo change its site? Is there a fix for the problem?
This is the Error:

Having the same issue (script was still working correctly yesterday)

[MaximilianPannenbaecker]

Ah okay so maybe yahoo changed something

[lironsamara]

Also having the same issue - getting it for different stocks each time. Any solution?

Thanks!

[matt-wetmore]

Same issue here

[HeadbangerFinance]

I'm also getting a lot of issues/problems since yesterday - however, seems to be working when I disable threading...

[groszek1604]

The same problem, threading worked for 5-10 tickers, then the same issue

[ftamimi]

Same issue, seems like most requests work fine but some give this error - looks pretty random, same ticker will work one minute then fail. I can't try and catch - it seems to be stuck and I need to ctrl c to remove the error. I've tried show_errors=False, threading=False but still the same

started yesterday

[tavianix]

Same issue here, I try 0.1.63 and 0.1.64, yesterday everything worked fine...

[danieldeconinck]

Same here. Since yesterday. Works with a couple of tickers but fails randomly after multiple request. "threads=False" does not help

[seekingclarity]

Ditto. Same issue. It worked on a portfolio of tickers a few times then I received a similar error as above and the following error as well on a different portfolio:

timeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

[matt-wetmore]

threading=False seemed to help for me; I run my tickers in batches of 100 and a few of those still crashed on the first try after I added threading=False in, but they all eventually worked, whereas last night they didn't no matter how much I tried.

[AlexisMinerscience]

You can try to use the construction (try: … except: …) together with threading=False, as a temporary measure it works for me.

[MaximilianPannenbaecker]

Well at least it is not just myself. Thanks for the tip

[ftamimi]

I've got try: except: but for some reason I see the error and have to ctrl c, then it gets to the except print message I have, otherwise it doesn't go past the error

Thanks. Worked fine for me also
