Updated code part. ps. the chatClientToken has expired. when I start testing i always use the latest token.

const chatClientToken = "AQICAHgDPFqoWS2jdOfTGB1Vo7NQnk0RhxoHKwei87S3M72_WgGXpV-mDgAwwUJ2UdCY15ZUAAAB0TCCAc0GCSqGSIb3DQEHBqCCAb4wggG6AgEAMIIBswYJKoZIhvcNAQcBMB4GCWCGSAFlAwQBLjARBAyJQR2ruBPj-WXSeyACARCAggGE1gSj19XcIQPV30V8wF15YmAk7Rac086esruMblXDKabrTC2UdanFCksa4aE62SeppjmhKleGNSvXUH0IajebRu4FvsflOgldfAEto8Kmum_--y7JnM0pRiefk03tXpFI9mXGhQ0AY8sbsw1gZIeg4xttXq7umQKEYef3bpsD-nC_pEcFyFPz6ilkNPVjZNaPRK_jBikhvyVImCh7x1PT3LGa8j8xhKtzGZdY1LzNgnbS9x8Q7rNmeekhkZtOaI04sMsxVIHRJlT9fGvdpkeompQo_IbUU_-Kf4YhIEROSnRSH1qSzOztUmjD33K18L5xmFnorgYCM_CsNydLMuxv8s2ygFJeOiJ-_J358y1Qmr6AdMZT-xI7lBhVftubxQ-LAwL3Hs-NPqIlq079MbH4xw1YmH8yJ56V28AKl0NfVavMWMhfwRepr2BiSUd6gQyE6rB2Y2MbQp3c4C-gMvlMAwPYMBesbTb9kCQQP-Qz2Qz5L4ZsLgJZ04kvlSVXqezFxOoNDQ!!#0";

It is possible that the chat token you are using to connect to the chat room has expired. Can you provide more information about the error? What HTTP status code is returned? Here is a list of the possible errors you may receive. You might want to also decode the token using https://jwt.io to verify that it looks good and is not expired.
